SUMMARY

This discussion focuses on analyzing a complex circuit involving a 10 Ω resistor, a 2 µF capacitor, and multiple switches (S1, S2, S3). Key calculations include determining the energy delivered to the resistor over a specified time period and the energy stored in the capacitor at steady-state. The participants emphasize the importance of using Kirchhoff's laws (KCL and KVL) and the relationship between power and energy to solve the problems effectively. The discussion concludes that resistive elements dissipate energy while capacitors store energy, and integration is necessary to find energy delivered over time.

In a direct current circuit, once steady state has been reached the capacitors are fulled charged and current no longer flows to them. In that case, yes.

okay, that answered my question.

Thanks again Doc Al
