Question

An electric motor takes 5 A from a 220 V line. Determine the power of the motor and the energy consumed in 2 hrs.

Answer 1

Electric current = 5 A

potential different = 220 V


Time = 2 * 60 * 60 = 7200


===================================================


P = VI

220 * 5 V
=> 1100 w



________________________________________________________



Energy consumed by motor
=> 1100 * 7200
=> 7.92 * 10^6 J


________________________________________________________


=> 7.92 * 10^6 J

==>ι = 5a
==>v=220 v
==>т = 2нrѕ = 2*60*60=7200ѕec

==>power = vι = 5 *220 = 1100 w anѕ

==>p = w /t
==>1100 = w /7200
==>w =7920000 joυle anѕ
