For a heater, rated 4 kW and 220 V, calculate the following:
The current

For a heater rated at 4kW and 220V, calculate: (a) the current, (b) the resistance of the heater, (c) the energy consumed in 2 hours, and (d) the cost if 1kWh is priced at Rs 4.60.

An electric heater has a rating of 3 kW, 220 V . Calculate the following (i) Current. (ii) Resistance offered by the heater. (iii) Cost of running the heate for 10 hours at the rate of ₹ 3.50 per unit.

A heater draws 1100 W at 220 V.Calculate the kilowatt hours consumed in a week if the heater is used daily for four hours at the rated voltage .

Two lamps rated 100 W, 220 V and 10 W, 220 V are connected in parallel to 220 V supply. Calculate the total current through the circuit.

In a house having 220 V line , the following appliances are operating : (i) a 60 W bulb, (ii) a 1000 W heater , and (iii) a 40 W radio. Calculate (a) the current drawn by the heater and (b) the current passing through the fuse in the main line.

An electric bulb is rated 220 V and 100 W. Calculate the power consumed when it is operated on 110 V.

The rating of an electric heater is1100 w, 220V calculate the resistance when it operates at 220 v, also calculate the energy consumed in kwh in the month of November, if the heater is used daily for 4 hours at the rated voltage.

Two lamps rated 100W,220V and 25W,220V are connected in parallel to 220V supply. Calculate the total current through the circuit.

Two lamps, one rated 100 W at 220 V, and the other 60 W at 220 V, are connected in parallel to electric mains supply. What current is drawn from the line if the supply voltage is 220 V?
