Thank you so much!

thank you!

Hello, I'm abit confused Shouldn't you divide the voltage by 2 in the table , since the current changed to zero not negative ?

[@ETphysics]

It isn't done changing yet! When the current change to zero, the time interval is still half way. Hence if the change in flux is half, in half the time, the rate of change is still the same.

Hey can u prepare a worksheet regarding cosmology? It’s a new topic added and there are no qs available

[@SwagDaddy-ku6em]

There are questions on it in Pre-U papers

How can we figure out the direction of current?

[@teeshajairam5741]

It always moves from positive terminal to negative terminal
