For the ideal RL circuit shown, the resistance is R=10.0Omega, the inductance is L=5.0 H and the battery has voltage xi_("bat") = 12volts. Some time after the switch S in the circuit is closed, the ammeter in the circuit reads 0.40A. If the rate at which energy is being stored by the inductor at this instant is (16)/(x) Watts, what is the value of x? |
