The current through a conductor is 1 ampere when the temperature is `0^(@)C` and 0.7 ampere when the temperature is `100^(@)C`. What would be current when the temperature of the conductor is `1200^(@)C` ?

When current passes through a conductor,

Ohm's law is valid, when the temperature of the conductor is

When a current flows through a conductor its temperature

When electric current passes through any conductor, then its temperature is

When no current is passed through a conductor,

A hot body is kept in cooler surroundings. Its rate of cooling is 3^(@)C /min when its temperature is 60^(@)C and 1.5^(@)C / min when its temperature is 45^(@)C . Determine the temperature of the surroundings and the rate of cooling when the temperature of the body is 40^(@)C

The amount of heat conducted out per second through a window, when inside temperature is 10^(@)C and outside temperature is -10^(@)C , is 1000 J. Same heat will be conducted in through the window, when outside temperature is -23^(@)C and inside temperature is:

The temperature of a room heated by heater is 20^@C when outside temperature is -20^@C and it is 10^@C when the outside temperature is -40^@C . The temperature of the heater is
