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

Electronics and Communication Engineering (ECE) : Electronic Devices and Circuits - Quiz(MCQ)

Correct Answer : Option (B) : 2V

Explanation : We know that, P_DC=V_DC²/R_L. So, V_DC=(P_DC*RL)^1/2=10000^1/2=100V.
Here, ϒ=0.02
ϒ=V_AC/V_DC=V_AC/100.So, V_AC=0.02*100=2V.
