In the circuit below, V = 6 volts, R = 10 ohms, L = 100 mH. The switch has been open for a long time. Then, at time t = 0, the switch is closed.

What is the time constant for the current through the inductor?

2L / R

2. Relevant equations

TAU=l/R

3. The attempt at a solution

I am not sure how do I find the equvialent resistance in this case.
