Homework Statement



In a typical lightning strike, 2.5 C flows from cloud to ground in .020 ms. What is the current during the strike?

Homework Equations



I've been doing 2.5 C / .0002 s = 12,500. However, this is not right.

The Attempt at a Solution



Am I using the wrong formua? This problem seems so easy I don't know where I'm messing up.

Hello csimon current =charge/time so it seems you are using the correct formula.The time is 0.02ms=0.00002s not 0.0002ms
