Half-wave rectifier:
A half-wave rectifier is a circuit that converts an alternating current (AC) voltage into a pulsating direct current (DC) voltage. It allows only one half of the input waveform to pass through and blocks the other half.
Frequency of the alternating voltage:
The frequency of the alternating voltage is given as 50 Hz. This means that the voltage alternates its direction 50 times in one second.
Number of pulses of rectified voltage:
To determine the number of pulses of rectified voltage obtained in one second, we need to consider the half-wave rectifier circuit.
In a half-wave rectifier, only the positive half-cycle of the input voltage is allowed to pass through. This means that for every full cycle of the input voltage, only one pulse of rectified voltage is obtained.
Since the frequency of the input voltage is 50 Hz, this means that there are 50 cycles of the input voltage in one second. Therefore, the number of pulses of rectified voltage obtained in one second is equal to the number of cycles of the input voltage, which is 50.
Hence, the correct answer is option 'B' - 50 pulses.
