In the following circuit, the input voltage Vin is 100 sin(100πt). For 100πRC = 50, the average voltages across R (in volts) under steady-state is nearest to
-
- 100
- 31.8
- 200
- 63.6
Correct Option: C
The given circuit is voltage doubler,
| Here | Vin = 100 sin (100πt) |
| ↓ | |
| (Vm) |
∴ Vm = Voltage across each capacitor = 100 V
∴ Voltage across two capacitors (in steady state)
= 2Vm = 2 × 100 V = 200V
| ∴ Average voltage across ‘R’ = | = 63.6 V | |
| π |
