Write commercial and SI units of energy. Calculate the cost of electric energy consumed by an electric heater rated with 50 W used for 2 hours daily in the month of April. The cost of one unit of electric energy is Rs. 5.

Two electric bulbs of 100 W each is used for 10 hours in the month of June. Write the following steps in sequential order to find the numbe of units of electricity consumed in the month of June. (A) The number of units of electricity consumed by both bulbs in the month of June is the total elec-trical energy consumed by bulbs expressed in W h divided by 100 W h . (B) Note the rated power of each electric bulb, time of electrical consumption of each bulb per day from the given data. (C ) We know, one electrical unit = 1 kW h or 1000 W h . (D) Calculate the amount of electrical energy con-sumed by both the bulbs in the month of June using, (sum of the electrical power of both the bulb) xx (time of consumption in one day) xx 30 days.
