Question

Current 4 ampere is flowing through a conductor of resistance 2 ohm the electrical energy consumed is 5 seconds

Answer 1

Answer:

0.0000416kW/h

Explanation:

As we know that P=I^2×R

P=(4)^2×2=32W

1W=1/1000kW

32W=32/1000kW

P=0.032kW

Time=5 sec =5/60×60h

=5/3600h=0.0013h

and,E=P×t

=0.032×0.0013kW/h

=0.0000416kW/h
