A full-wave rectifier is used to convert 50 Hz A.C into D.C, then the number of pulses per second present in the rectified voltage is

Options

A. 50
B. 100
C. 200
D. 400

Answer

To solve the problem of determining the number of pulses per second present in the rectified voltage from a full-wave rectifier converting 50 Hz AC into DC, we can follow these steps:

### Step 1: Understand the Input Frequency
The input frequency of the AC signal is given as 50 Hz. This means that the AC signal completes 50 cycles in one second.

### Step 2: Determine the Output Frequency of a Full-Wave Rectifier
A full-wave rectifier converts both halves of the AC waveform into positive voltage. Therefore, for every cycle of the AC input, the rectifier produces two pulses in the output.

### Step 3: Calculate the Number of Pulses
Since the input frequency is 50 Hz, and each cycle produces 2 pulses in the output, we can calculate the output frequency as follows:
- Output frequency = 2 × Input frequency
- Output frequency = 2 × 50 Hz = 100 Hz

### Step 4: Conclusion
Thus, the number of pulses per second present in the rectified voltage is 100 pulses per second.

### Final Answer
The number of pulses per second present in the rectified voltage is **100 pulses/second**.
