twoelectric bulbs rated 25W, 220V and 100W, 220V are connected in series across a 220V voltage source. find out the power drawn by individual bulbs(p1, p2)

as w = vi,  25 = 220*current
current = 25/220 for p1
for p2
current = 100/220
r = v/i
resistance for p1 = 2202 / 25 and for p2 = 2202 / 100

now claculate the net resistance in the circuit and then calculate the current required
calculate the voltage drop on each of the bulbs p1 and p2 and then multiply it with the current
You will get the answer – power for p1 = 16w and power for p2 = 4w
