Can we apply the superposition theorem to AC circuit?

Hereâs how you can apply the superposition theorem to an AC circuit:

1. **Turn Off All Sources Except One:** For each independent AC source in the circuit, replace all other independent sources with their internal impedances (for ideal voltage sources, replace them with short circuits; for ideal current sources, replace them with open circuits).

2. **Analyze the Circuit:** Solve the circuit with only the single active AC source to determine the voltages and currents.

3. **Repeat for Each Source:** Perform the above steps for each independent source in the circuit.

4. **Superimpose the Results:** Add the contributions from each source algebraically (considering both magnitude and phase) to find the total voltage and current in the circuit.

Remember that for AC circuits, youâll need to take into account both the magnitude and phase of the voltages and currents. If you're working with phasors, you can perform the superposition in the phasor domain and then convert the results back to the time domain if needed.
