A full wave rectifier circuit consists of two p-n junction diodes, a centre-tapped transformer, a capacitor and a load resistance. Which of these components removes the AC ripple from the rectified output?
- AA centre-tapped transformer
- Bp-n junction diodes
- CCapacitor
- DLoad resistance
Solution & Step-by-step Explanation
After rectification, the output is pulsating DC (contains AC ripples). A capacitor connected in parallel with the load acts as a filter, as it blocks DC but provides a low-reactance path for AC components, thus smoothing the output.
