An inductor coil carries a steady state...

An inductor coil carries a steady state current of 2.0 A when connected across an ideal battery of emf 4.0 V. if its inductance is 1.0 H, find the time constant of the circuit.

Text Solution

Verified by Experts

The resistance of the circuit = R = `(4)/(2) = 2Omega`
`therefore` The time constant = `tau = (L)/(R ) =(1)/(2) = 0.5 ` s
