Question

An electric motor is 5 ampere from a 220 volt line determine the power of the motor

Answer 1

using formula

p=v*I

p=220*5

p=1100w

or

firstly calculate R

by using formula

R=V/I

R=220/5

R=44 ohm

now using formula

p=i^2*r

p=5*5*44

p=25*44

p=1100 w

hope you will get!!

mark it as brainlist pls

Answer 2

GIVEN

• Voltage (V) = 220 V
• Current (I) = 5 A

FORMULA TO BE USED

• P = V × I

POWER CALCULATION

P = 220 x 5

P = 1100 W

RESULTS

• Power of the motor = 1100 W
