3 lamps rated 240V 60W,240V 75W,240V 100W respectively are connected in series across a 240V supply. Calculate the voltage across each lamp and power output from each lamp.

Answer : Req= (1/1200 +1/560 + 1/2.1)^-1 = 2.1 ohms RT= 2.1 + 7.8 = 9.9 ohms IT = V/R = 24/9.9 = 2.4 A Veq= R I = 2.1 2 ... 7.8 = 12.096 w = 44.928 w _________________________________________ By: Ellis-Junior Kamatjipose ellisjuniork90@gmail.com...
