Question

An electric bulb is marked 60 watt 220 volt. how much current will be flow connecting the bulb from Electric Main of 220 volt. how much heat will be produced in 5 minutes ​

Answer 1

Answer:

Explanation:

P=60 W

V=220 V

T=5 min=300 s

I=P/V

I=60/220

I=0.27 A

H=VIT

H=220*0.27*300

H=17820 J

Answer 2

P=I×V

I=220/60=3.67amp

now,V=I×R

R=220/3.67=60ohm

heat=I²rt

=3.67×3.67×60×5×300

=242460joule
