A 11 V battery is connected in series with a resistance of 9.4 and an inductance

Question

A 11 V battery is connected in series with a resistance of 9.4 and an inductance of 5.3 H.
Find the energy stored in the inductor one time constant after the switch is closed. An- swer in units of J. A 11 V battery is connected in series with a resistance of 9.4 and an inductance of 5.3 H.
Find the energy stored in the inductor one time constant after the switch is closed. An- swer in units of J. Find the energy stored in the inductor one time constant after the switch is closed. An- swer in units of J.

Explanation / Answer

          Given that the voltage of battery is V = 11V            Resistance is R = 9.4            Inductance is L = 5.3 H -----------------------------------------------------------          Energy storedis U = (1/2)LI2                                      =(1/2)L(V/ R)2                                           =(1/2)(5.3H)( 11V/9.4)2                                             =3.62 J                                         =(1/2)L(V/ R)2                                           =(1/2)(5.3H)( 11V/9.4)2                                             =3.62 J
