[@AdeoluwaAdeyemi-sx7ju]

I've watched 3 of your videos now and i love them(that on mechanica, plotting graph and this)....which do you advice one does, optics(light) or electricity ma?

[@JoynuelPhysics]

I prefer mechanics and electricity

[@AdeoluwaAdeyemi-sx7ju]

@@JoynuelPhysics thank you very much

[@speaklord023]

Well done mea

[@JoynuelPhysics]

Thanks so much

[@idowuogunrinde7361]

Good presentation. More wisdom in Jesus name.

[@JoynuelPhysics]

Amen, thanks so much

[@johnidris8010]

Thanks for this. But where exactly do we touch the jockey on the meter bridge?

[@JoynuelPhysics]

U re welcome.
There's a 100cm meter rule on the meter bridge. And there's a wire on the meter rule. Place the jockey on the wire.

[@Emmanueljacob-xi1pq]

In the Constantine wire on the meter bridge

[@HelenJohn-ki9qe]

Thanks for sharing
Please ma I need lesson on how to create table of observation
Thanks

[@HelenJohn-ki9qe]

Pls do on mechanics too
Thanks allot ma

[@JoynuelPhysics]

Thanks dear, will create a video on that

[@Oyinz356]

Lovely video. Please can you do for maths?

[@JoynuelPhysics]

Thanks so much, if time permits me before maths day, l will.

[@Oyinz356]

Thank you ma

[@Oyinz356]

Especially math's theory please 🥺

[@AjayiOluwashina-si1rb]

You ought to measure 100cm of the wire first before fastening it to the terminals.

[@JoynuelPhysics]

That was what l did. Thanks

[@chrisapathy6202]

you did well ma,
please ma, where could I buy such your metre bridge.
tried with materials I have but the galvanometer reading was unidirectional. Pls.

[@JoynuelPhysics]

Check Finlab online. I don't know if they have branch in your location.

[@Nneme-owajiSimeon]

The video has been a blessing but your camera angle could be worked on

[@JoynuelPhysics]

Yes, thanks so much

[@nyemunganmario5607]

This video is awesome but the camera work is bad

[@JoynuelPhysics]

Thanks so much, will do more and better camera work in the next video.

[@Campus_lifestyle]

Someone should do the 📷 work I think that is what he meant.
Good job.
Am an academic laboratory TECHNOLOGIST in Uniport

[@udemejohnson9602]

Good job ma God bless you More grace to your elbow ma
Ma pls I want to ask where was this question repeated in past question
Tnxs ma

[@JoynuelPhysics]

Thanks so much, bless you too. Will have to check my past question again this morning to be exact

[@MarkEroh]

Good day ma'am, ur doing well but I just observe ur connection to the METER-BRIDGE I think 🤔 the -ve terminal of the galvanometer should go to the METER-BRIDGE while the +ve leg/terminal should go to the jock key

[@JoynuelPhysics]

Thanks so much for your observation, will do more practice with my students connecting that way. Thanks so much

[@yusufwisdom7396]

I think her connection is right going by the circuit diagram. Connecting it the other way might swap the values

[@onuwaachris6279]

your illustrations are really understandable... I enjoyed the session...... thank you so much ma......
but In taking scales for instance, is it 2cm represent 2 unit or 2cm represent ohms........ thank you ma, once again

[@JoynuelPhysics]

U re welcome.
In choosing scales, 2cm can represent any convenient scale that you can plot. Use any convenient scale, is allowed.

[@JoynuelPhysics]

Thanks so much, 2cm represent for instance 2units is correct. The unit of the quality like ohms will be in the axis.

[@adewumiblessing1031]

On the graph dont you think the values on the vertical axis is too clustered? Just my thought though

[@JoynuelPhysics]

Physics values are always close

[@truth1162]

Thanks for this video madam but please the area where we told to evaluate k=√s was not done

[@JoynuelPhysics]

Yes, please finish it up. I was rushing not to make the video too long

[@EipegaSamuel-vq4lq]

What can we now expect as the question that follow after the precaution?

[@JoynuelPhysics]

Definition of resistivity,, calculation under resistivity of wire

[@NwigweSolomon-fk2yg]

Nice one but you didn't show us how to solve the other questions

[@JoynuelPhysics]

Thanks so much, bear with me. I was rushing not to make the video too long

[@kolawolesegun6845]

Well done ma. Can we use Wheatstone bridge instead of metre bridge to carry out the experiment?

[@JoynuelPhysics]

Thanks so much. Meter bridge will give accurate result more than wheatstone bridge.

[@omoilestanley9441]

Please for the rheostat , is there any specific adjustment needed

[@JoynuelPhysics]

No, just placed it to the max, so the galvanometer can be deflecting.

[@ochochomeogheneruemugba4044]

Can I used a wheatstone bridge instead

[@JoynuelPhysics]

Meter bridge gives more accurate results. Wheatstone bridge might not provide the same level of precision

[@jeremiahopadeji6629]

Well done ma but isn't the negative terminal galvanometer meant to be connected to the terminal of the metre bridge

[@JoynuelPhysics]

I connected the jockey there, thanks for watching

[@kareemoluwakemi4241]

Thanks for the video ma❤Sorry Ma is it students that will make all the connections on the exam day

[@JoynuelPhysics]

Yes, but the teachers are also allowed to be present for practicals .

[@Deinamaechi]

Well done!
Please could you do a video on question 2, which is on optics.
Thanks!

[@JoynuelPhysics]

U re welcome.
I did for all the questions. Here is the link for question 2
ua-cam.com/video/HWdoZh8_Xus/v-deo.htmlsi=uyZdNWK58BPcRFBr

[@Deinamaechi]

Okay, thanks seen!

[@AlbertBabatunde]

my meter bridge has one port at each end

[@cirujano-yj1uv]

ma shld we do all readings one table?

[@JoynuelPhysics]

We will follow the instruction from WAEC on that day. Best wishes.

[@musbaudeenlawal5870]

What is d function of d rheostat ,second resistance wire

[@JoynuelPhysics]

The rheostat provides control over the current and ensures protection over sensitive instruments like the galvanometer and meter bridge.
The second wire was also used towards the ending part of the experiment. R for the first wire was compared with R for the second wire.

[@adewoleadebola6563]

Please ma do you remove the key from the switch after taking your reading and then put it back again

[@JoynuelPhysics]

Yes, always do that

[@hakeemadejare4818]

​​But will the readings be affected if one decides to leave the key from the switch close always throughout the experiment???​@@JoynuelPhysics

[@MercyGbagir]

I'm having issues with my connections. The galvanometer isn't reading to zero and each time I place my jockey, the galvanometer reading is always giving the same readings for the different lengths of the copper and Constantine

[@JoynuelPhysics]

Check your connection, ensure tight connection. Maybe there's a gap somewhere. Do you have another galvanometer? In case that one is faulty. Well done, I'm glad you are making good effort.

[@MercyGbagir]

@@JoynuelPhysics it has worked now... Thank you ma... Tomorrow is their physics practical.. thanks alot ma

[@JoynuelPhysics]

Best wishes to all our students

[@joya6204]

U block most of it acts with your body pls change the camera guy but d video is good

[@JoynuelPhysics]

Thanks so much, will do so

[@Oyinz356]

Sorry please what's the difference between the two wires? Is it their material?

[@Oyinz356]

Sorry I've seen the difference

[@Oyinz356]

I've subscribed to your channel. Thank you ma

[@JoynuelPhysics]

Constantine wire have more resistivity than copper wire.
There are physical differences too, in their colour and thickness. Copper wire is thin, light and different in color .

[@Oyinz356]

Oh I see. Thank you very much❤️

[@BlendGodson]

Your video does not capture the details of the experiment process. Please kindly consider that when you are making your videos

[@JoynuelPhysics]

Alright, thanks so much

[@Campus_lifestyle]

I think,Anyone coming to watch his video is assumed to have a background knowledge of the experiment. Making video like this u have have focus.. there is a lot to this .. this is just a quick guide

[@AnthonyJuliet-tr2tk]

The video was nice but you literally blocked some of the important parts with your body so please next time ensure that all parts of the video is clear.Thank you.

[@JoynuelPhysics]

Thanks so much

[@anabathomas5033]

Please explain it small small

[@JoynuelPhysics]

Alright, thanks so much

[@faithezuruike123]

Good job but you block the whole thing with your back.

[@JoynuelPhysics]

Thanks so much. Will position the camera better next time.

[@adewumiblessing1031]

I thought calculated values are supposed to be to 3 s.f

[@bull7890]

I think so

[@JoynuelPhysics]

Yes, u are right. U can as well leave all the values in your table in 2dp

[@princegodwin2110]

But ma, you didn’t evaluate for K

[@JoynuelPhysics]

I was trying to manage time, u can finish it up please

[@iveokoro4630]

i find it hard understanding electricity

[@JoynuelPhysics]

Is not hard, try to know circuit symbols. Once you follow the circuit diagram and do your connection, the rest will be very easy.

[@EmekaJoshua-ru3sq]

Your camera man is not doing a good job

[@JoynuelPhysics]

Will do better, thanks

[@adewoleadebola6563]

Your video is not capturing all the processes

[@JoynuelPhysics]

Was trying to save time, will do more next time

[@victorfrank4923]

Well done ma
