Basically the electricity that comes to our house or to any other place of energy distribution networks forms a large circuit with lines connecting to the power plant that forms an end called the hot wire and the lines connecting to the ground forming the other end. The electric charge flows between these two lines and the potential develop between them. The connection of loads that offer resistance to this load flow completes the complete circuit and the entire electrical system inside the house works without problems, as long as the devices have sufficient resistance and do not cause overcurrent. The short or excessive load flowing through the circuit or the sudden connection of the hot end wire to the ground wire would heat the wires, causing fire. To avoid such situations a circuit protection is used which simply cuts the remaining circuit in such conditions.
