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.

PREREQUISITES
  • Understanding of AC circuit analysis
  • Familiarity with differential equations in electrical engineering
  • Knowledge of phasor representation of voltages and currents
  • Basic concepts of RC circuit behavior
NEXT STEPS
  • Study the derivation of the forced response in RC circuits
  • Learn about the voltage-current relationship in capacitors
  • Explore the use of phasors in AC circuit analysis
  • Investigate the impact of frequency on the behavior of RC circuits
USEFUL FOR

Electrical engineering students, circuit designers, and anyone interested in understanding the dynamics of RC circuits and their forced response in AC analysis.

Homework Statement



what is the forced response for Rc cct. and how to derive it??

Homework Equations



I know that the forced response in RL cct. is :
i = cos (ωt - tan^-1

we start from :

Vm cos (ωt) = Ri + L

and

i = I am cos (ωt-θ)

Can anyone help please!

just give me the voltage of capacitor law.
I don't know how to start,
 
It's not clear from your description what it is you're trying to do. Are you trying to write and solve the differential equation for the current in a series RC circuit? Or do you just want the steady-state AC response (AC current given the AC driving voltage)? Something else?
