The Superposition Theorem cannot be directly used for the calculation of:

The superposition theorem applies strictly to linear systems where responses are directly proportional to inputs ($V = I R$). Power is a non-linear, quadratic function of current or voltage ($P = I^2 R = \frac{V^2}{R}$); therefore, total power cannot be calculated by summing individual power dissipations ($P_{total} \ne P_1 + P_2$).
