1.	Differentiatebetween short -circuitingand overloading .
Answer» Solution :Short -ciruiting: If the plasticinsulation of thelivewires come in neutralwire getseither directlyor via a conductingwire . Thisthouchingof the live wire and neutral wire is known as short -circuiting . In this case , the resistance of the circuit becomes almostzero. This results in the flow oflarge currentin the circuit . This heats up wiredangerously and may lead to FIRE. Overloading: The currentflowingin dometic wiringat a particular time depends on the powereletrical appliances of high POWER ratinge.g., electric iron , water heater , air- CONDITIONER , etc are switched on at the sametimetheydraw an extermelylargecurrent from the circuit . Thisis CALLED overloading . Thereforethe copper /aluminium wireof householdwiringget HEATED to a veryhightemperature . Thiscan lead to fire.
