What is the output voltage at the end of the input pulse from an RL integrator that uses a 2 H inductor, a 10 kΩ resistor and a 32 V, 0.4 ms input pulse?
A)13.9 V
B)27.7 V
C)21.6 V
D)19.0 V

Quizplus · Accepted Answer

The output voltage of an RL integrator at the end of the input pulse can be calculated using the formula Vout = Vin * (1 - e^(-t/τ)), where τ = L/R. Here, τ = 2 H / 10,000 Ω = 0.0002 s. Substituting the values, Vout = 32 V * (1 - e^(-0.0004/0.0002)) = 32 V * (1 - e^(-2)) ≈ 27.7 V.
