A power transmission line feeds power at 2200V with a current of 5A to a step down transformer with its primary winding having 4000 turns. Calculate the number of turns and the current in the secondary in order to get output power at 220V. Share with your friends Share 5 Chetna answered this 400 turns and current is 50A -2 View Full Answer Anandhi answered this Given, input power (Vp ) = 2200V Number of turns (n1) = 3000 Output power (Vs) = 220 V vs/vp = n2/n1 implies, 220/2200 = n2/4000 n2= 400 ∴ Number of turns in the secondary winding, n2 = 400 turns. -1 Anandhi answered this Ip/Is = vp/vs so, Ip/5 = 2200/220 ip = 5*10 = 50 A -4 Shreya answered this Ns/Np=Vs/Vp and given to us Np =4000 , Vs =220 & Vp=2200 therefore Ns= Np x Vs Vp Ns= 4000 x 220 2200 =>Ns= 400 turns. Is=Vs xIp Vp => Is= 220 x5 = 0.5A 2200 -4 Neeraj Gupta answered this Ns = 400 turns Is = 50A Output power = 11000 watt 2
