If a half wave rectifier is used to convert 50Hz AC into DC, then the number of pulses present in rectified voltage is:
Correct answer: B. 50
- A. 25
- B. 50
- C. 100
- D. 75
Explanation
Rectifiers produce unidirectional and pulsating voltage from A.C. source, the number of pulses per second in the rectified voltage remains same as that of input voltage, i.e., here it is 50 Hz.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
