Really concise video. Thank you so much- saved me from a nervous breakdown

I have a question, what happens to the potential difference in a parallel circuit containing branches with components of different resistances?

[@am-hc3de]

it remains same oon parallel

[@TechGeniusTege]

Thankyou this really helped me understand the concept of the experiment

[@Omar-st4dw]

In theory, u should connect a fixed resistor in series with the cell. why didnt u do that or is it not required ? thanks :)

[@Omar-st4dw]

No, I meant the one I series with the cell.

[@orchibasu9598]

I believe it is to not cause any damage to the cell as it would heat up the battery which could (a) skew results by a changing emf (b) cell/battery could explode due to increasing temperatures.

@@Omar-st4dw This is simply to indicate the internal resistance of the cell
