What is the time constant of a 50mH inductor in series with a 200 ohm resistor?

Answer 1

You need to convert the inductance value to henry. Then, simply divide the inductance by the resistance.

Answer 2

The time constant (τ) of a circuit consisting of an inductor (L) and a resistor (R) in series is given by the formula τ = L/R. In this case, with L = 50mH and R = 200 ohms, the time constant would be τ = (50mH) / (200 ohms) = 0.25 milliseconds.
