1. The problem statement, all variables and given/known data In a typical lightning strike, 2.5 c flows from cloud to ground in 0.20 ms. What is the current during the strike? 2. Relevant equations I = Q/t 3. The attempt at a solution The reason I keep getting this wrong is because it says I am rounding something off wrong. I am very confused. What I keep getting is 2.5 C/0.0002 s = 12500 A. Anyone know what I'm doing wrong?
