Current passing through 3 Omega resistance is

Current passing through 3 Omega resistance is

Find the heat produced in joule if a current of 0.1 A is passed through a coil of resistance 25 ohm for one minute.

An immersion heater with electrical resistance 7Omega is immersed in 0.1 kg of water at 20^@ C for 3 min. If the flow of current is 4 A , what is the final temperature of the water assuming whole of heat produced is consumed in water. (Specific heat capacity of water = 4.2 xx 10^(3) J kg^(-1)K^(-1) )
