The power rating of an electric motor which draws a current of $3.75\, A$ when operated at $200\, V$ is about:

$A$ $12 \text{ HP}$ motor has to be operated $8 \text{ hours/day}$. How much will it cost at the rate of $50 \text{ paisa/kWh}$ in $10$ days? (in $Rs.$)

If the current through a resistor in a circuit increases by $3 \%$,then the power dissipated by the resistor

If the resistance of the filament increases with temperature,what will be the power dissipated in a $220\, V- 100\, W$ lamp when connected to a $110\, V$ power supply?

$A\, 5\, ^oC$ rise in the temperature is observed in a conductor by passing some current. When the current is doubled,then the rise in temperature will be equal to ............. $^oC$.

If the current in an electric bulb is changed by $1\%$,then the percentage change in power will be ............. $\%$.
