Question
A sinusoidal voltage signal of $10 \mathrm{~V}$ peak is applied across a resistor of $25 \Omega .$ What power is dissipated in the resistor?
Step 1
First, we need to find the RMS (Root Mean Square) value of the sinusoidal voltage signal. The RMS value is given by the peak value divided by the square root of 2. Vrms = Vpeak / √2 Vrms = 10V / √2 Vrms ≈ 7.07V Show more…
