SUMMARY
The forced response of an RC circuit is derived from the steady-state AC response, where the current can be expressed as i = I_am cos(ωt - θ). The discussion emphasizes the importance of understanding the differential equation governing the current in a series RC circuit, particularly in relation to the voltage across the capacitor. The key equations referenced include Vm cos(ωt) = Ri + L, which are essential for deriving the forced response in this context.
