An elastic heater of resistance `115ohm` is made to work on 230 V supply
Calculate the power of this heater.

An elastic heater of resistance 115ohm is made to work on 230 V supply Calculate the heat generated by this heater if it works for 10 minutes.

An elastic heater of resistance 115ohm is made to work on 230 V supply What will be the current through this heater while it is working.

An electric heater of resistance 8Omega draws 15 A from the service mains 2 hours. Calculate the rate at which heat is developed in the heater.

How much current will an electric bulb draw from 220 V source if the resistance of the bulb is 1200 Omega ? lf in place of a bulb, a heater of resistance 100 Omega is connected to the sources calculate the current drawn by it .

An electric bulb is rated at 60W, 240V. Calculate its resistance. lf the voltage drops to 192 V, calculate the power consumed and the current drawn by the bulb. (Assume that the resistance of the bulb remains unchanged).

In a household, an electric bulb of 100W is used for 10 hours and an electric heater of 1000W is used for 2 hours Calculate the cost of using bulb and heater for 30 days take the cost of one unit of electrical energy is 5 rupees.
