Alternating Current vs Direct Current

Q1:

The duty cycle of a square wave with a pulse width of 3 mu.gifs and a period of 9 mu.gifs is 40%.

A True

B False

ANS:B - False

Mukesh is correct you are wrong, as you said duty cycle = Ton/(Ton+Toff) or Ton/Total Period.

In the problem, Ton and Total Period is given as stated explicitly "a PULSE WIDTH of 3μs and a PERIOD of 9μs" Pulse width pertains to the "on time" while period means the total period.

Therefore,
Duty Cycle = (3μs/9μs)*100% = 33.333%.
