Answer 1

Answer

A heating coil is immersed in a calorimeter of heat capacity $\sf 50 J {°C}^{ - 1}$ containing 1.0 kg of a liquid of specific heat capacity $\sf 450 J \: \: { {kg}^{ - 1} \: \: °C}^{ - 1}$. The temperature of liquid rises by 10°C when 2.0 A current is passed for 10 minutes. Find :

(i) the resistance of the coil,

(ii) the potential difference

across the coil.

State the assumption used in your calculations.
