(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known dataSo this is from a past test put up as a study guide, but I'm stumped here. The question is:

A spark jumps between two electrodes, transferring a charge of 5 μC in 2 × 10−3 s. The

constant current I that would transfer the same charge in the same time is

3. The attempt at a solution

The solution is 2.5e-3A.

What is the formula to use? Is this to be treated as a capacitor therefore U=1/2QC? Just need a nudge to get my head around it for the test Tuesday.

Thanks
