The power dissipated in an a.c. circuit with an r.m.s, current of 5A, r.m.s voltage of 10V and a phase angle of 60o is
Answer Details
The power dissipated in an AC circuit can be calculated using the formula P = Vrms × Irms × cos(θ), where Vrms and Irms are the root mean square values of voltage and current respectively, and θ is the phase angle between them. Here, Vrms = 10V and Irms = 5A, and the phase angle is 60°. So, the power dissipated is P = 10V × 5A × cos(60°) = 25W. Therefore, the answer is 25W.
