What I have trouble understanding is why the formula for the total power is \(P_{T}=\frac{(E_{c})^{2}}{R}+\frac{(E_{m})^{2}}{2R}\) and not \(P_{T}=\frac{(E_{c}+2E_{m})^{2}}{R}\) because the former formula kind of contradicts the result obtained when applying the superposition principle.

Thank you for your time.
