Question

14.* A heating coil is immersed in a calorimeter of heat
capacity 50 J°C- containing 1-0 kg of a liquid of
specific heat capacity 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.​
