Hi.
Thanks for the reply.
I am working through the question:
A cell of emf 3.0v and negligible internal resistance is connected to a 4.0 Ohm resistor in series with a parallel combination of a 24.0 Ohm resistor and a 12.0 OHm resistor. Calculate:
-the total circuit resistance (which I've...
Hi.
As part of my as physics work i have to calculate the 'cell current', but we haven't covered this in class.
I have searched on google but nothing has come up.
If somebody could point me in the right direction, i'd appreciate it.
Thanks.
