can superposition theorem be applied to a circuit containing one ac and one dc source
Answers
Answer:
Because AC voltage and current equations (Ohm's Law) are linear just like DC, we can use Superposition to analyze the circuit with just the DC power source, then just the AC power source, combining the results to tell what will happen with both AC and DC sources in effect.
Answer:
When ckt is linear, we can apply superposition theorem whether the ckt is DC or AC. Superposition theorem applies to AC ckt the same way it applies to DC ckt. In case of AC ckt we have to take impedance instead of simply resistance as in case of DC. This theorem becomes even more important in case of AC ckt having two or more sources operating at different frequency. In this case since the impedance depend on frequency, we must have a different frequency domain ckt for each frequency (simply due to different frequency impedance will be different). The total response is due to sum of individual responses.
