$A$ piece of fuse wire melts when a current of $15\, A$ flows through it. With this current,if it dissipates $22.5\, W$,the resistance of the fuse wire will be .............. $\Omega$.

Two electric lamps of $40\, W$ each are connected in parallel. The power consumed by the combination will be ........... $W$.

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 $\Delta t$?

According to Joule's law,if the potential difference across a conductor having a material of specific resistance remains constant,then the heat produced in the conductor is directly proportional to

Heat produced in a wire of resistance $R$ due to current flowing at constant potential difference is proportional to

$A$ heating element is designed to dissipate $2400 \, W$ when connected to $240 \, V$. The power it dissipates when it is connected to $120 \, V$ is (Assume that resistance of the filament is constant). (in $ \, W$)
