For a sinusoidal input voltage, V_s = V_m sin ωt = √2 V_s sin ωt
if the input voltage is connected to load for n cycles and is disconnected for m cycles, then rms output voltage is given by
V_o = V_s √K
where duty cycle K is given by

1. m + n
2. m – n
3. mn
4. n
  m + n

Correct Option: D

= V_s √K

∴ K =	n
	(n + m)
