If i had an inductive-resistance circuit with a Vbat of 6v?

Question

R of 10ohms and A solenoid L=0.10mH how would i work out the time constant of the circuit and its significance? i also dont know how to work out the steady state voltage of this circuit thanks for ur help anyone

Answer 1

V = 6 volts

R = 10 ohms

L = 1.00E-04 henrys

TC = L / R = 10 / 1.00E-04 = 1.00E-05 sec

The significance of the time constant is that it will take 1.00E-04 seconds for the circuit to achieve steady state current when it is switched on.

Solenoids are used in door bells, so a door bell with this circuit would cause a "ding" of about 1.00E-05 seconds.
