Alternating Current and Voltage - Engineering

Q1:

The duty cycle of a pulse waveform with a pulse width of 10 µs and a period of 100 µs is 25%.

A True

B False

ANS:B - False

Duty cycle = [Ton/(Ton + Toff)] * 100. = (Pulse width/Total time period) * 100.

Given: Ton = 10us. T = 100us.

Duty cycle = (10/100)*100 = 10%.

So answer is FALSE (B).
