Question

One lamp is rated 40 W at 220 V and the other 60
W at 220 V. These two lamps are connected in
parallel to a 220 V supply. Calculate the current
drawn from the supply line by each lamp.​

Answer 1

Answer:

power,P = 40W

potential difference ,V =220V

current,I = ?

P = V×I

40 = 220×I

40÷220 =I

I =0.18A

II nd bulb

P = 60 W

V = 220V

I = ?

P = V×I

60 = 220×I

60÷220 =I

I =0.27 A

Answer 2

power 1:40w

power2:60w

p difference:220v

parallel connection

current:?

I:i1+i2

p:v*I

Current is equal to 0.45amphere

hope you will be satisfied with my answer....
