a current of 4A flows in a wire of resistance 60 ohm. calculate electrical energy consumed in 2 min.

Power dissipated = energy/second= (current)² x (resistance) Power dissipated = energy / second = (4)² x (60) = 960 joules per second= 960 wattsEnergy = (power) x (time) = (960 watts) x (2 minutes) x (60 sec/minute)                  = 115,200 joules
