When a current flows through a conductor,its temperature:

An amount of charge $Q$ passes through a coil of resistance $R$. If the current in the coil decreases to zero at a uniform rate during time $T$, then the amount of heat generated in the coil will be,

What is the ratio of heat generated in resistors $R$ and $2R$ connected in parallel as shown in the figure?

How much work is required to carry a $6 \mu C$ charge from the negative terminal to the positive terminal of a $9 V$ battery?

$A$ steady current $I$ flows through a wire of radius $r$,length $L$ and resistivity $\rho$. The current produces heat in the wire. The rate of heat loss in a wire is proportional to its surface area. The steady temperature of the wire is independent of

If the length of the filament of a heater is reduced by $10\%$,the power of the heater will
