 Sumedha said: (Dec 23, 2011) How? please explain.

 Nil said: (Dec 30, 2011) What is the formula?

 Sri said: (Jan 17, 2012) Pulsewidth is total duration of positive cycle dutycycle=pw/total period= 10us/100us = .1

 Vivek said: (Jan 20, 2012) Mr. Sri how can you say that the pulsewidth is total duration of positive cycle because for total duration we calculate or add the time of -ve & +ve pulse and both this pulse is count in one cycle of wave (0-2#) , threfore m nt agree with your answer.

 Pavan Siva Kumar said: (Jun 18, 2012) The formula for calculating the duty cycle is Ton/ (Ton+Toff). From the Question it is clear that pulse width (Ton) is given as 10 us and the total period is (Ton+Toff). So, the Duty cycle is = Ton/ (Ton+/Toff) = (10 us/100 us) *100= 10.

 Pradeep said: (Nov 2, 2012) Duty cycle is a time reuired for one+&-ve half cycle.

 Alankar said: (Mar 4, 2013) Here the whole period that mean Ton and Toff is 100ms and the pulse width Ton is 10ms. The formula is written in other comments.

 Jay Purohit said: (Apr 27, 2013) Duty Cycle = Ton/(Ton+Toff). We have Ton=10us. Toff=10+10=20us. So duty Cycle = 10/(20) = 0.5*100 = 50%.

 Smritimoy said: (Jun 10, 2013) Duty Cycle = Ton/(Ton + Toff) = Pulse width/Period = 10/100 = 0.1 Equivalent to 10%.

 Raji said: (Jul 4, 2013) 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.

 Kanika said: (Oct 22, 2013) Duty cycle = pw/time period = 10/100 = 1/10 = .1x100= 10%.

 Shorav said: (Oct 1, 2016) 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).

 Kamal said: (Dec 19, 2016) Yes, duty cycle is 10%.

 Ravi Rathod said: (Mar 28, 2019) Duty cycle = on time/ on time + off time so * 1 00. 10/ 110 = 0.09 * 100 = 9.0.

 Jeevani said: (Jul 19, 2019) Duty cycle = (high time/pulse width) * 100.
