Question

Technician A says that the waveform produced by an ac generator after rectification is called a sine wave. Technician B Says that the waveform produced by the ac generator after the output moves through the diodes is a straight line because it is a constant dc voltage. who is correct?

A.Tech A
B.Tech b
C.A and B
D. neither a nor b

Answer 1

Neither Technician A nor B is correct.

Answer: Option D

Explanation:

In AC generator, diodes are usually used to rectify the alternator current. This is the transformation into direct current from alternating current. Sinusoidal voltage is generated by generators when it rotates in both directions. The output voltage
`V_(i n)` is converted to DC with diode help.

This process is called rectification. The output voltage
`V_(i n)` is treated as the input signal of the diode circuit. So, after rectification, the sine wave is not produced by an AC generator. And, the sine wave resulted by AC generator when the output passes via diodes and not a straight line.
