$A$ $10\, V$ storage battery of negligible internal resistance is connected across a $50\,\Omega$ resistor. How much heat energy is produced in the resistor in $1$ hour? (in $J$)

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 ............. $\Omega$.

Find the number of electrons flowing through the filament of a $120 \ V, 60 \ W$ electric lamp in one second.

The maximum current that flows through a fuse wire before it blows out varies with its radius as

Two electric bulbs are connected one by one across a potential difference $V$. At that time,the power consumed in them is $P_1$ and $P_2$ respectively. Now,if the potential difference $V$ is applied across the series combination of these bulbs,what will be the total power consumed?
