Toaster

Vedclass · Answer

(A) We know that the formula for resistance is $R = \frac{V^2}{P}$,where $V$ is the voltage and $P$ is the power.Assuming the voltage $V$ is constant for both appliances,the resistance $R$ is inversely proportional to the power $P$,i.e.,$R \propto \frac{1}{P}$.For the toaster,$P_1 = 1\, kW$.For the electric heater,$P_2 = 2\, kW$.Since $P_1  R_2$.Therefore,the $1\, kW$ toaster has a greater resistance than the $2\, kW$ electric heater.

Out of the two,a toaster of $1\, kW$ and an electric heater of $2\, kW$,which has a greater resistance?
