The circuit below is a series connected RLC circuit. At t=0, the switch moves from position 1 to position 2.

For this circuit:

Write the KVL that governs this circuit after for t>0, following the indicated current iR, and using the passive power convention to define component voltages (vR, vL, vC).

Your answer might look like: vR - vL + vC - 1 = 0
