If current flows for time t then the production of heat is given as H = I2R.t Where I = current = 1 A R = Resistance = 10 ohms t = time = 5 sec H = 12 × 10 × 5 H = 50 watt-sec or Joule
The cutting pliers used for electric work should be provided with the insulating material such as plastic, Rubber etc. so that the person can be remain save from the electric shock.
