Out of the two, a toaster of $1\, kW$ and an electric heater of $2\, kW$, which has a greater resistance ?
Out of the two, a toaster of $1\, kW$ and an electric heater of $2\, kW$, which has a greater resistance ?
We know that $R =\frac{ V ^{2}}{ P }$ or $R \propto \frac{1}{ P } .$ Thus, the
$1\, kW$ toaster, has more resistance than a $2\, kW$ electric heater.
