Question

An electric fan of 750 watt is connected with 220V main line and used for 10 hours . Find the amount of electric energy consumed in BOT unit .Also find the resistance of the electric iron..Please solve..​

Answer 1

Explanation:

Power=750w

V=220volts

P=Vx I

I=P/V

=750/220

=3.40A

By ohm's law, we have V=IR

R=V/I

=220/3.40

=64.7 OHMS.

THEREFORE, The current passing through circuit is 3.40A and Resistance =64.7 OHMS.

Answer 2

Answer:

GIVEN:

Power=750w

V=220volts

P=Vx I

I=P/V

=750/220

=3.40A

By ohm's law, we have V=IR

R=V/I

=220/3.40

=64.7 OHMS.

THEREFORE, The current passing through the circuit is 3.40A and Resistance =64.7 OHMS.
