Does the superposition theorem apply to power?
2 Answers
The superposition theorem primarily applies to linear circuits for analyzing voltages and currents, not directly to power. While you can use it to find the individual contributions of sources to voltages and currents, power is a nonlinear function of voltage and current (P = VI).
When you have multiple sources, you can find the total current or voltage using superposition, but to find the total power, you need to calculate the power for each source separately and then combine them, keeping in mind that power cannot be simply added due to its nonlinear nature.
In summary, use superposition to find voltages and currents, and then calculate the power based on those values for each source.

The Superposition Theorem applies to linear circuits to determine the contribution of each independent source (voltage or current) to the total response. It doesn't apply directly to power because power is a nonlinear function of current and voltage (P = IV). In linear circuits, you can use superposition to find individual voltage or current contributions, but you'll need to combine these to find the overall power, usually requiring more complex analysis.
