An electric immersion heater of $1.08 \,kW$ is immersed in water. After the water has reached a temperature of $ 100^{\circ }\,C, $ how much time will be required to produce $100\, g $ of steam?

The temperature (T) dependence of resistivity (p) of a semiconductor is represented by

A piece of wire of resistance $R$ is cut into n equal parts. These parts are then connected in parallel. If the equivalent resistance of the parallel combination is $R'$ , then $\big(\frac{R}{R'}\big) $ is

There is a current of $40\, A$ in a wire of $10^{-6} \,m ^{2}$ area of cross-section. If the number of free electrons per cubic metre is $10^{29}$, then the drift velocity is
