Question
(a) Find a symbolic expression for the potential difference ?VL across the inductor, when crossing the inductor in the direction of current flow. (Use the following as necessary: L, I0, t and ?).
The current through a solenoid having self-inductance L is given by I(t) = I0 e-t / tau. Find a symbolic expression for the potential difference Delta VL across the inductor, when crossing the inductor in the direction of current flow. (Use the following as necessary: L, I0, t and tau). Delta VL(t) = Let L = 41.0 mH, I0 = 59.0 mA, and tau = 2.40 ms. Determine the voltage across the inductor at each of the following times. At t = 0.00 ms. Delta VL = V At t = 1.50 ms. Delta VL = V At t = 3.00 ms. Delta VL = V At t = 4.50 ms. Delta VL = v
Explanation / Answer
V = L*di/dt)
V = - [ L*I0*exp(-t/tau) ] / tau
