1. The problem statement, all variables and given/known data I'm trying to use the equation for charging capacitor that's discharging, and I can't get the answer right. On the calculator it keeps showing as 1. 2. Relevant equations I(t) = -(1.96) [e^((-9.0*10^(-6)) / (1300)(2.0*10^(-9)))] 3. The attempt at a solution My problem is that the exponential part keeps coming out as the value 1 when I input it into the calculator. I need help on solving the exponential part.
