If $2.2\,kW$ power is transmitted through a $100\,\Omega$ line at $22,000\,V,$ the power loss in the form of heat will be ............. $W$.

The heat produced by a $100\, W$ heater in $2\, minutes$ will be equal to:

$A$ resistor develops $500 \, J$ of thermal energy in $20 \, s$ when a current of $1.5 \, A$ is passed through it. If the current is increased from $1.5 \, A$ to $3 \, A$,what will be the energy (in $J$) developed in $20 \, s$?

$A$ rise of temperature of $4\,^oC$ is observed in a conductor by passing a current. If the current is tripled,the rise in temperature will be .............. $^oC$.

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

When the power delivered by a $100\,V$ battery is $40\,W$,the equivalent resistance of the circuit is ........... $\Omega$.
