An LR combination is connected to an idal battery. If l = 10 mH, R = 2.0 Omega and epsilon = 2.0 V, how much time will it take for the current ot reach 0.63 A?

An L-R combination is connected to an ideal battery. If L = 20 mH, R = 100 Omega and epsilon = 10V , find (i) the time constant (ii) the maximum current and (iii) the time elapsed before the current reaches 90% of the maximum value.

A L-R combination is connected to a battery of emf 4 volt. If L = 0.1 H and R = 4.0 Omega , then the time taken to reach a current of 0.631 ampere is:-

A solenoid has an inductance of 50 mH and a resistance of 0.025 Omega . If it is connected to a battery, how long will it take for the current to reach one half of its final equilibrium value?
