Homework Statement
Current flowing through an element is i(t)= 2e^(-t) and voltage across that conductor is v(t)= 2 (di/dt). Find out the charge is delivered to the element and power and energy consumed by the element in between 0 to 3 seconds.
Homework Equations
i(t) = dq/dt
power = v * i
Energy = power * time
The Attempt at a Solution
I got charge,q = 1.9 C
For power, I got voltage as -4 e^(-t), multiplying it with current, and I got Power as -8 e^(-t) but i must be getting the answer in some number right?
And what about energy? I don't have power till now, so couldn't calculate it.
