RLC 6-14-2020

Electricity and Magnetism Level 3

In the RLC circuit shown below, the capacitors and inductor are de-energized at time $t = 0$ . From then on, power flows out of the DC voltage source for most of the time, but for a brief time, power flows into the source.

What is the largest instantaneous power flowing into the source?

Details and Assumptions:
1) $V_S = 10$
2) $R_1 = 4$
3) $R_2 = 1$
4) $C_1 = 1$
5) $C_2 = 1$
6) $L = 1$
7) Give your answer as a positive number
