प्रश्न
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?
उत्तर
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.
