For an ideal conductor, thermal resistance is :
Compare equations for rate of flow of heat through a conductor and current through a conductor and write the expression for thermal resistance.
What is the resistance of an ideal voltmeter and ideal ammeter?
Match the resistances that an ideal conductor offers at different temperatures.
Thermal conductivity of the conductor shown in the figure is 0.92 cal/cm s∘C. Find the thermal resistance between points P and Q (in s∘C/cal).
A thermally insulated rigid container contains an ideal gas. It is heated through a resistance coil of 100Ω by passing a current of 1 A for five minutes, then change in internal energy of the gas is
