Question

Out of the two a toaster of 1 kilowatt in an electric heater of 2 kilowatt which has greater resistance

Answer 1

Hi please mark it as brilliant answer is 1:2

Answer 2

Answer:

As $R = \frac{V^2}{P}$. If V is constant, then R ∞ $\frac{1}{p}$ i.e. more power, lesser is the resistance and vice-versa.

The toaster has lesser power( 1 KW ) than the electric heater( 2 KW ) and therefore the resistance of the toaster is more than the resistance of the heater.
