Question

A circuit has a line of 5 A. How many lamps of rating 10W ; 220 V can simultaneously run on this line safely?

Answer 1

110 lamps... is the correct answer

Answer 2

hey mate!

here is your answer:

power=10w

voltage=220v

current=power/voltage

current=10/220

current =0.045 ampere

current in circuit=5ampere

lamps that can simultaneously work=5/0.045=111.111

i.e 111 bulbs .

hope it helped^_^
