Question

The potential difference between the terminals of an electric iron is 240 V and the current is 5.0 A. What is the resistance of the electric iron?

Numerical

Solution

The potential difference between the terminals of an electric iron is 240 V and the current is 5.0 A.
So resistance 

R=VI 2045

=48 Ω 

`R=V/I=240/5=48Ω`
Thus, the resistance of the electric iron will be 48 Ω.
