Question

In half wave rectification, what is the output frequency if
the input frequency is 50 Hz.​

Answer 1

Answer:

Given:

A Half Wave rectified circuit has been provided with frequency of input AC current = 50 Hz

To find:

Output frequency of current.

Concept:

First of all , what's the function of half wave rectifier circuit.

• It converts the bidirectional AC current to a unidirectional Pulsatile current .
• This helps in proper functioning of various devices like Phone chargers.

Calculation:

First look at the attached graph to understand the input and output characteristics.

Frequency refers to how rapidly a cycle has been completed.

On the input characteristics , one cycle has been completed in 1 time period.

Similarly , in the input characteristics , one cycle is completed in 1 time period.

So the rapidity of cycle completion remains same. Hence the frequency remains same.

$\boxed{ \large{ \sf{ \green{ \therefore \: output \: freq. = 50 \: hz}}}}$

Answer 2

Answer:

Half Wave rectifiers are formed by the use of a single P-N junction diode . This prevents bidirectional flow of current. This passes the current through the load resistor along a single direction.

Also an capacitor is added along the resistor to prevent excessive pulsatile character of the current.

Now Output Frequency in Half wave rectifiers are same as that of Input frequency. This is because same number of cycles are completed in a specific. time period.

So output Frequency = 50 Hz
