Question

Two bulbs are rated 60w 220v and 40w 220v calculate current

Answer 1

We know , P=IV
I= P/V
I=60/220 = 3/11 A
I=40/220 = 2/11 A

Answer 2

Hi there !!

Bulb 1 :-

Power = 60 W
Voltage = 220 v

Power = Current x Voltage
60 = I x 220
I = 60/220
= 0.27 Amperes

-----------------------------------------------

Power = 40 W
Voltage = 220 v
Current , I = Power / voltage
= 40/220 = 0.18 Amperes
