What amount of heat will be generated in a coil of resistance $R$ due to a charge $q$ passing through it if the current in the coil decreases to zero uniformly during a time interval $\Delta t$?

An electric bulb is rated $60\,W$,$220\,V$. The resistance of its filament is ............. $\Omega$.

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

In an electric heater, $4\, A$ current passes for $1\, \text{minute}$ at a potential difference of $250\, V$. The power of the heater and the energy consumed will be, respectively:
