The 505 a current through a 150 h inductor is dissipated by, Ask an Expert

Academics

The 5.05 A current through a 1.50 H inductor is dissipated by a 1.89 Ω resistor in a circuit like that in the figure below, with the switch in position 2.

1645_A current through a inductor is dissipated.gif

(a) What is the initial energy in the inductor?

(b) How long will it take the current to decline to 5.00% of its initial value?

What is the energy when the current is 5.00% of the initial current? How is average power defined in terms of initial and final energies?
