Consider the circuit given below where Rf is the diode forward resistance and RL the load resistance. What is the average rectified current equal to?
-
- Vm /(RL + Rf)
- Vm /{π(Rf + RL)}
- 2Vm /π
- Vm /{ 2(RL + Rf)}
Correct Option: B
The given circuit
The above circuit is half wave rectifier. Therefore
| Var = | π |
| Iar = | = | π | (RL + Rf) |
Hence alternative (B) is the correct choice.
