Question

an electric iron draw a current of 0.4A when a connected to a 200V supply .Find the resistance of the heat element of an electric iron. What current would the iron draw when it is connected to a 240V supply​

Answer 1

Answer:

Resistance is 500 ohm

Current is 0.48A

Explanation:

I=0.4

V=200V

V=I R

R=V/I

=200/0.4

=500 ohm

I=V/R

=240/500

= 0.48 A

Answer 2

Answer:

Resistance is 500 ohm

Current is 0.49A

Explanation:

I=0.4

V =200v

V=IR

R=V/I

R=200/ 0.4

R= 500ohm

I= V/R

I= 200/500

I=0.48A
