(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

If the current in the inductor 10mH decreases exponentially from its

initial value of 14 A with a time constant of 3 seconds, what is the voltage

across the inductor at the instant when the current reaches 7 A?

2. Relevant equations

V(t)=L di/dt

3. The attempt at a solution

di = 7, dt=3

thus

V=(10e-3)(7/3)=0.0233v

Am I correct? Seems to be too simple for me
