Hello everyone, new to the boards here and I'm looking for some help with an Inductor question.
Here is the question.
I'm given the equation for power stored, W = (1/2)Li^2
In which i is a function of the voltage in which i = 1/L * integral of V*dt
1st off I switched the L = .5H, then at given time 100ms, the Voltage is 30V
So I did i = 30V/.5H = 60 for the current
then inputed it into the W equation and got .5*.5*(60^2) = 900J
but 900 isn't the correct answer.
Can someone point out where I went wrong?
