In an RL series circuit, an inductor of 4.74 H and a resistor of 9.33 Ω are connected to a 26.4 V battery. The switch of the circuit is initially open. Next close the switch and wait for a long time. Eventually the current reaches its equilibrium value. At this time, what is the corresponding energy stored in the inductor? Answer in units of J.

The energy is  

Explanation:

From the question we are told that

   The inductor is  

    The resistance of the resistor is

    The voltage of the battery is

Generally the current flowing in the circuit is mathematically represented as

=>  

=>  

Generally the corresponding energy stored in the circuit is  

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.
