Hi, thanks for the reply. This is a sub question on a rather larger topic of superconducting magnets. I understand that these magnets can be run in persistent mode, whereby the power source is removed, and due to superconductivity, the current will remain flowing indefinetly. As soon as...

Basically, but don't forget the last stage of the theorem: the square root! So many marks are lost due to this!

Hi this is my first post so please be nice :) 1. Homework Statement The problem has been set up that a circuit containing a resistor and switch is being driven by a power source of unkown potential. The switch is flick to short the power source leaving only the resistor in a closed loop...
