If $2 \times 10^{-3} J$ of work is done in moving a particle carrying a charge of $10 \times 10^{-6}$ coulomb from infinity to a point $P .$ What will be the potential at the point $P ?$

Define power. State the difference between $1$ watt and $1$ watt hour. Establish the relationship between unit of electric energy and $SI$ unit of energy. An electric heater rated $1000\, W / 220 \,V$ operates $2$ hours daily. Calculate the cost of energy to operate for $30$ days at the rate of ₹ $5.00$ per $k W h$
