I=V/R
I=220/40
I=5.5A
Flow of current in each bulb=I=5.5A
I=5.5A through 4 bulbs
each bulb=1.375 A
I=220/40
I=5.5A
Flow of current in each bulb=I=5.5A
I=5.5A through 4 bulbs
each bulb=1.375 A

total power of 4 bulbs = 40W
power of one bulb = 40/4 = 10W
ELECTRIC POWER = POTENTIAL DIFFERENCE × CURRENT
10 W = 220V × I
I = 10/220
I = 1/22
I = 0.04545........55 A
power of one bulb = 40/4 = 10W
