Heya buddy!!!
Here's the answer to your questions...
=>A volt is a unit used to measure the force of an electric current.1 volt is the potential difference when 1 joule work is needed to be done to carry 1 coulomb of charge.
=>Overloading: Every supply has a capacity to bear a maximum load, i.e., the power that can be supplied has a limit. Sometimes, the number of appliances which are switched on at the same time have power more than the capacity of the line. This is called overloading. In this situation, wires of the supply get heated due to extremely large current flowing through them and the circuit may catch fire. To avoid this fire, we use an electric fuse in the circuit. The current in a circuit depends on the rating of the appliances connected to it.
=>Short circuiting: Whenever live and neutral wires come in contact with each other, the incident is called short circuiting. In this case, resistance of a circuit decreases to a very small value. The decreasing of resistance increases the current. Due to this increased current, the wires get heated. This extreme heat may cause fire in the building.
=>The difference in electric potential between two points is known as Potential difference.
(Relation)-> The potential difference between two points in an electric field is defined as amount of work done in moving a unit charge from one point to other point.
=>An example of a parallel circuit is the wiring system of a house. A single electric power source supplies all the lights and appliances with the same voltage. If one of the lights burns out, current can still flow through the rest of the lights and appliances.
The most common everyday series circuits are the electrical circuits found in homes and vehicles. Water heaters use a series circuit. Freezers and refrigerators both use series circuits. Lamps also operate on a series circuit.
HOPE IT HELPS!!!✌️
