Question

state the factors on which the peak value of alternating emf depends

Answer 1

Answer:

The more the AC waveform departs in smoothness from a square wave, the higher will be the likely peak value of the AC voltage. Obviously the highest peak voltage will be the case where the entire voltage exists for only a very short time interval in each voltage half-cycle.

Explanation:

Answer 2

Answer:

Peak value of alternating emf depends on

1. The percentage of each voltage half cycle in which the voltage value contributes to the effective value.

2. The smoothness of the voltage waveform

Explanation:

A perfect square wave in which peak volatge will be equal to the effective voltage provides lowest peak value for effective Well, for a given value of effective alternating emf or AC voltage.

If the AC waveform will move smoothly from the square wave it will provide high peak value of alternating emf . Hence, when the whole voltage or emf exists for short time interval in each emf cycle, there will be The higtest peak emf.

Thus the two important factors in which peak value of alternating emf depends are:

1. The percentage of each voltage half cycle in which the voltage value contributes to the effective value.
2. The smoothness of the voltage waveform.
