I am a Physics teacher and I am preparing my students for the WAEC Physics practical.
You are doing a quality job.
Keep it up!
You have literally made my job easier, later today.

[@SundayAigbiremonlen]

According to the theory of the experiment as the length of the cable decreases the balance point increases. Maybe you need to check your connection.

[@vindalsacademy]

I will go to the laboratory to check again. Well thanks for the observation

[@omokifuemiadeleye5199]

Sir should we cut off the remaining part of the wire that's not needed after tying? I asked because I wonder if it would affect the results of the experiment also I'm not sure if we'd have enough wire on the D day

[@vindalsacademy]

Yes just measure 100cm and work with it.

[@vindalsacademy]

After measuring 80, 70 don’t cut it. It won’t affect the reading

[@abionamercy5306]

What is the Amp and ohm of the rheostat that should be used for the experiment sir?

[@vindalsacademy]

It was not specified by the exam body. But, I am suspecting that they may tell us to adjust the the rheostat to a certain value using ammeter. That is why they said and other necessary materials. That is my opinion

[@AguIjeoma-ho9uv]

Well done, 👍it would really help

Thanks for this Bro. Do you have an Idea about where I can get those blue and red connecting cables?

[@vindalsacademy]

You may not get exactly this one. But, just ask of a small wires. Red and black

[@Adeymolahubs]

Thanks so much sir

[@Oyinz356]

Sir after tying the wire should we cut off the part that's not needed? I asked because I'm wondering if it would affect the results of the experiment. Also I'm not sure if we'd have enough wire on that day yet

[@vindalsacademy]

Yes. Just measure only 100cm and use it for the rest of the experiment

[@vindalsacademy]

[@LawalAbdurrahmanOlatunde]

But it is said that as one slides the jockey over the potentiometer it reduces the cross-sectional area of the wire or what do u think

[@Joshua-ds8xz]

Thank you sir for that but I will need more explanation on those experiments

[@vindalsacademy]

Yes I will do one more experiment. Part two of the electricity.

[@vindalsacademy]

But help me share the videos to encourage me to do more.

[@obadofinsamson7793]

Good one. Does the constantan wire on one metre bridge affect the determination of the balance point compared to another metre bridge. I purchased a new metre bridge for my school, its thickness of the constantan wire differs from the old metre bridge and their readings are so far apart.

[@vindalsacademy]

@@obadofinsamson7793
Yes because different wires have different resistance so different balance points

[@israeleshovo]

Good job sir, what about experiment on Relative density and triangular glass prism

[@vindalsacademy]

I am working on that one soon it will be made available

[@itzmikael]

Appreciate the video sir...can you do one on Archimedes principal

[@vindalsacademy]

Sure now guy. I am working on it. Just that the apparatus will be today.

[@NayigaHawa-xq2se]

@@vindalsacademy practicals like when determining the ratio of internal resistance of a dry cell to the resistance per meter of the wire provided and another is when determining the resistivity of the bare wire and how to read ameter and voltmeter plus plotting graphs, thanks

[@udamagodwin4937]

Good job, but the values of LX are too high, I think they should not go beyond 47cm for any length of resistance wire

[@vindalsacademy]

Yes there was a problem with that reading. Go to examguide. Where I did the correct version. So sorry about that

[@vindalsacademy]

Or just check my last video. Part 2 of the electricity

I love it but always let the camera be close thank you

[@dunukenechukwu999]

Why aren't you using the wire on top of the metre rule on the metre bridge

[@vindalsacademy]

That wire is rusty. So the conductivity is poor

[@AmakaObinwa-xt7ml]

Pls can u show us alternative to practical incase no apparatus

[@vindalsacademy]

Very sure when I will be plotting the graph. I will explain the questions.

[@chrisapathy6202]

my galvanometer deflects only in one direction on all position of the metre bridge

[@chrisapathy6202]

what could be the problem of galvanometer deflecting only in one direction, I bought another galvanometer but does not resolve the problem of the unidirectional motion

[@vindalsacademy]

Adjust the position of your rheostat

[@vindalsacademy]

To see what happens next

[@onyemachristopher4335]

What material is the first wire made of.
Please what is the aim of the practical

[@OlayinkaAnimashaun-ns4dv]

Well-done,but there's so much manipulation in the experiment.I guess physics practical is not as easy as it seems....once thank you for the insight!

[@vindalsacademy]

Some are not easy to manipulate

[@BaronJay-cz9dg]

Which year in waec past question can i see a similar question to this?

[@okwudilisunday43]

thanks tou chaiman. But the thing doesnt run smoothly at all with another wire of another materialeg copper

[@vindalsacademy]

Because every wire has different resistance.

[@user-tx3rf7uv5b]

Can potentiometer be instead of meter bridge

[@vindalsacademy]

It's not part of the apparatus.

[@abuhjohn8688]

A potentiometer can't do the work of a metre bridge,you can check New school physics for more explanation

Is dis correct question

[@daviduc7573]

How can i get this type of connecting wires?

[@vindalsacademy]

It must not be this kind I am using. Any laboratory wire can do a good job.

[@daviduc7573]

Just that I like connecting heads for easy connections

[@omokiikan]

Please sir where did you get the connecting wires and how much does it cost?

[@vindalsacademy]

I can supply for you if you want. But again go to any electrical store ask of red and black wire

[@omokiikan]

@@vindalsacademy how much does it cost? If you want to supply?

[@riwoggia.r140]

Video is good. But the rheostat has not been resolved, you only guessed a point on the rheostat to have a reading on the Galvanometer.

[@vindalsacademy]

Remember Waec said other necessary materials. They may request that a certain amount of current is recorded.

[@vindalsacademy]

So don't worry okay

[@vindalsacademy]

Thank you Femi. Please share the video

[@SundayAigbiremonlen]

Your connection is wrong , according to the theory of the experiment, as the length of wire decreases , the balance point increases.

[@vindalsacademy]

@Sunday thank you for that observation, I will go back to the lab to check and I will respond accordingly. Once again thanks

[@ayobamioluseun5527]

I couldn't get the zero point on the galvanometal with this connection

[@vindalsacademy]

@ayobamioluseun5527.
You have to try again. Check if all your apparatus are working well. Or just adjust your rheostat. Or check if the rheostat is connected wwll

[@vindalsacademy]

Sunday your comment is unfair. I have reconsidered the experiment. The principle is well followed. Resistance is directly proportional to the length of the wire.
