NECO Physics Practical 2024 on ELECTRICITY ( Question 3)

[@TebeereCharity]

Nice one

[@JoynuelPhysics]

Thanks for watching

[@excreted4396]

If she was my physics teacher i would never skip a class

[@JoynuelPhysics]

Thanks so much

[@DavidMayowa-rx3zs]

May God continue to grant you more grace, well explained.

[@JoynuelPhysics]

Thanks so much

[@MichaelAboka]

Well explained, I love this pattern of teaching.

[@JoynuelPhysics]

Thanks so much

[@MichaelAboka]

@@JoynuelPhysics You're welcome but, ma I have a question ❓, Good morning ma.

[@JoynuelPhysics]

@@MichaelAboka Good morning, was busy with my students

[@DavidMayowa-rx3zs]

Well explained and detailed with clearly simplified, may God bless you and strengthen you 🙏 amen.

[@JoynuelPhysics]

Amen
Bless you too

[@LovelyLabrador-bx7ux]

I really feel that you should be awarded for your uncanny precision, clear explanation, and your very good video quality. One more fascinating fact about you is that you are still humble and opened to correction, thank you ma❤

[@JoynuelPhysics]

Thanks so much, I'm encouraged. God bless you ❤️

[@Gamerboi0407]

Well done ma 'am , thanks so much

[@JoynuelPhysics]

You are most welcome

[@ceocreation]

Your teaching is always outstanding, and you simplification is always top notch. Well done!

[@JoynuelPhysics]

Thanks so much

[@JimohRidwanullah]

Grateful ma'am... understandable

[@JoynuelPhysics]

Glad to hear that

[@klassy_joanna]

So accurate this is what I need this moment may God continue to bless you ma ❤🎉

[@JoynuelPhysics]

Amen
Bless you too

[@DANIELEJIKE-b7q]

Thanks so much

[@JoynuelPhysics]

You're welcome!

[@DANIELEJIKE-b7q]

👍👍

[@MosinmiloluwaOkuwa]

this was very helpful

[@JoynuelPhysics]

Thanks so much

[@Denz4real]

You got it right ma, God bless you

[@JoynuelPhysics]

Thanks so much, bless you too

[@AmahaAchile]

Good work ma'am, keep it up..God will strengthen you for us

[@JoynuelPhysics]

Amen, thanks so much

[@OlugbengaVictorOlotu]

Welcome ma, God will continue to increase your knowledge in Jesus mighty name, please note you may ask to find the intercept which may not necessary for the graph to pass through the origin we only need to get the line of best fit not necessarily targeting the origin in anyway. Welldone!!

[@JoynuelPhysics]

Amen
Thanks so much
If you watch the video, towards the end, l solved the theory to know the nature of the graph. From the theory l deduced the nature of the graph as y = mx . If it was y = mx + c, then, there will be intercept.
Also the best line of fit, fitted to the origin.
Thanks so much for commenting, it keeps me moving.

[@robertchukwuezi9625]

This woman is brilliant, I didn't even think in this line. Kudos Ma'am. I had to use potentiometer and I don't trust my results too.

[@JoynuelPhysics]

Thanks so much Sir

[@WorshipJehovahRapha]

You are blessed by God, keep shining ma'am. God bless you for all you do. I'm your number one fan❤

[@JoynuelPhysics]

Thanks so much.
God bless you too

[@davidpaulebiloma4811]

Nice work...keep it up ma,

[@JoynuelPhysics]

Thanks so much

[@chibuiks_publishing]

God bless you ma❤

[@JoynuelPhysics]

Thanks, bless you too

[@MahmuduIbrahim-xk9rg]

Niece one ma

[@JoynuelPhysics]

Thanks so much

[@Lazaruskalu-cd4vb]

Keep trying may the Lord through his infinity mercy bless you and give you good health of mind and body amen 🙏🙏🙏.I have learnt alot

[@JoynuelPhysics]

Amen
Thanks so much

[@ignatiusakpabio6142]

Fantastic

[@JoynuelPhysics]

Thanks so much

[@nwanjichristy3941]

More grace ma'am

[@JoynuelPhysics]

Amen, thanks so much

[@biyamasam]

Well done ma, from glory to glory. More Grace and wisdom in Jesus name, Amen.

[@JoynuelPhysics]

Amen, thanks so much

[@TokunboAdedeji]

Thanks so much ma

[@JoynuelPhysics]

U re welcome

[@israelokorawhe6618]

Thank you very much ma for all u do....up up u go.
I noticed u used 0-5v voltmeter but Neco said 0-3v....
I really enjoyed ur lectures...👍👍👍

[@JoynuelPhysics]

U re welcome
Yes, l used 0 to 5V, that is what we have in the lab.
Is still good, 0 to 3V is just to give you an idea of the range of voltage reading from the voltmeter. It doesn't affect anything. Thanks.

[@princeuweh8443]

But also, I thought the voltmeter reading should be reducing as you proceed??

[@MiracleAkenuwa]

Thank u ma🎉❤

[@JoynuelPhysics]

U re welcome

How to manipulate data for experiment involving use rheostst

[@Jossyscienceacademy]

Well done, dear. More grace

[@JoynuelPhysics]

Thanks so much dear

[@samsonolabode66]

Well job done, please ma'am is there any short ti get the values like using formula

[@JoynuelPhysics]

Thanks.
There should be but we have limited time

[@samsonolabode66]

I used the other formula but I didn't got the same values

[@OtunakpowhokeAfokeoghene-ze2so]

I felt like i was in the class with you there 😂 thanks soo much i enjoyed it

[@JoynuelPhysics]

I'm glad you enjoyed the video.

[@JustinaOsemene]

What about the number 2 practical

[@JoynuelPhysics]

This will help

[@gideonchiagozie-i5v]

Should we close the key before taking the reading of Vo

[@JoynuelPhysics]

Yes

[@kendoma1803]

Well done ma. But I think it is worth noting that any evaluation done should be calculated to at least 3 d.p

[@JoynuelPhysics]

Thanks so much

[@tundeadeleye1000]

Good job ma..
Is there a manipulation video for this practical please

[@JoynuelPhysics]

Thanks so much.
I haven't done a video on that yet but from the theoretical analysis I did at the end of the video, V can be calculated once Vo is known. Since E = 3V, using different lengths 20, 30, 40, 50 and 60cm respectively.

[@EipegaSamuel-vq4lq]

Is there any questions that will follow after taking the precautions?

[@JoynuelPhysics]

Yes, basic definitions like
Define resultant and equilibrant.
State parallelogram law of forces, state triangular law of forces...

[@EipegaSamuel-vq4lq]

@@JoynuelPhysics ma what of that of electricity own

[@IkeGeraldine]

Ride on ma

[@JoynuelPhysics]

Thanks so much

[@OgochukwuOzorma]

Good day Ma ,what about your R.

[@SolomonAyodele-ro7dv]

Ma please I need help in getting the refractive index for the physics report sheet

[@JoynuelPhysics]

The refractive index of rectangular glass block is 1.5
This video can help us

[@Jikemedumebichibuikem-gj5ey]

Why are we dividing 0.57 by 10?

[@FortuneAsike]

Please do you have the real question with you

[@olamidesubair4953]

Why is mine reading more than 3.0 on the voltmeter

[@JoynuelPhysics]

Check your connection, it shouldn't be more than 3V, that's why we were asked to provide 0 to 3V Voltmeter.
