In the below electrical circuit consisting of a resistor (R) and an inductor (L), the battery = 4V, the resistance R = 6Ω, and the inductor L = 0.5H.

At first, the switch has been connected to 1.  After a long time, it is switched to 2. 

1. At this moment, find the magnitude of the current through L. Then write the loop equation (using Kirchhoff’s rule) for the circuit.

2. Find the magnitude of the current through R  0.1s after the switch is moved to 2.
