Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Rectification is the process of converting Alternating Current (AC) into Direct Current (DC).
In a half-wave rectifier, only one half of each AC cycle (either positive or negative) is allowed to pass through, while the other half is blocked.
Step 2: Detailed Explanation:
The frequency of a periodic signal is the number of times the waveform repeats itself in one second.
1. For an input AC signal with frequency \(f = 60 \text{ Hz}\), the waveform repeats every \(T = 1/60\) seconds.
2. After passing through a half-wave rectifier, the output consists of a series of pulses followed by intervals of zero current.
3. Each "pulse + zero interval" combination corresponds to exactly one cycle of the original input wave.
4. Consequently, the output repeats its pattern with the same time period \(T = 1/60\) seconds.
5. Since the time period is unchanged, the frequency remains the same: \(f_{out} = 1/T = 60 \text{ Hz}\).
Step 3: Final Answer:
In half-wave rectification, the output frequency is equal to the input frequency, which is 60 Hz.
