Answer Posted / kbuuka john ivan (i.j.k)

Due to the loose connection,there is an air gap between the electrical contacts which results in high contact resistance.If current continues to flow,I2R loses(heat)will increase and later lead to melting of contacts and thus causing an open circuit.
Most electrical fires are mainly caused by a lot of heat that is generated as a result of loose connections.
