A full wave rectifier delivers 50W to a load of 200?. If the ripple factor is 2%, calculate the AC ripple across the load.

Question

Quizplus · Accepted Answer

The ripple factor is the ratio of the RMS value of the AC component to the DC component. Given the ripple factor is 2%, the AC ripple voltage can be calculated using the formula: Vr = Vdc * ripple factor. First, calculate the DC voltage (Vdc) using the power formula: P = Vdc^2 / R, where P = 50W and R = 200Ω. Solving for Vdc gives 100V. Then, Vr = 100V * 0.02 = 2V.
