Question

ripple factor of sine wave, square wave​

Answer 1

Answer:

ripple factor is the ratio of rms value of ac components present in the rectified output you the average value of rectified output. it is a dimensionless quantity a d denoted by Y. it's value is always less than unity,. this is basically a measurements of ripple which denotes the purity of rectified output.

Answer 2

Explanation:

QUESTION :-

Ripple factor of Sine wave and square wave.

ANSWER :-

Que : What is ripple ?

Ans :-

• Ripple is the fluctuating AC component present in rectified DC output. The output of a rectifier may either be DC current or voltage. In view of this, AC fluctuating component present in DC output voltage is called voltage ripple and that in DC current output is called current ripple.

Que : Why is Ripple present?

Ans :-

• Ripple is always present in the rectifier output. This is because of the behavior of circuit elements like diode or thyristor. Let us consider an example of single phase full wave rectifier to better understand the reason for presence of ripple. The output current waveform of single phase full wave rectifier is shown below.

• The expected output from full wave rectifier should be a pure DC but actually the output current is different. Since the average value of output current is the pure, therefore the ripple present is equal to the difference of output current or load current minus average current.

Que : What is Ripple factor ?

Ans :-

• Ripple Factor is the ratio of rms value of ac component present in the rectified output to the average value of rectified output. It is a dimensionless quantity and denoted by γ. Its value is always less than unity.
