How much time heater will take to increase the temperature of 100g water by `50^(@)C` if resistance of heating coat is `484Omega` and supply voltage is 220V a.c.

How much time heater will take to increase the temperature of 100g water by 50^(@)C , if resistance of heating coil is 484Omega and supply voltage is 220V

How much heat to be supplied to raise the temperature of 100 g water from 20^(@)C to the normal boilling point of water ?

The heater coil of an elecric kettle is rated at 2000W,200V, How much time will in take is rasing the temperature of 1 litres of water from 20^(@)C to 100^(@)C . Assuming that only 80% of the total heat energy produced by the heater coil is used in raising the temperature of water. Density of water heater coil is used in raising the temperture of water. density of water = 1g cm^(-3) and specific heat of water = 1 "cal" g^(-1) .^(@)C^(-1) .

How much current will an electric heater coil draw from 220 V source, if the resistance of heater coil is 110 Omega .

How much current will an electric heater coil draw from a 220 V source, if the resistance of the heater coil is 100 Omega ?

How much current will an electric heater coil draw from a 220 V source, if the resistance of the heater is 100Omega ?

How much current will an electric heater coil draw from a 220 V source, if the resistance of the beater coil is 100 Omega ?

An electric heater of resistance 10Omega connected to 220 V power supply is immersed in the water of 1 kg. How long the electrical heater has to be switched on to increase its temperature from 30^(@)C to 60^(@)C . (The specific heat of water is s=4200J kg^(-1) /C )

A 210 W heater is used to heat 100 g water. The time required to raise the temperature of this water from 25^(@)C to 100^(@)C is (specific heat capacity of water =4200" J/Kg-"^(@)C )
