The electric circuits and the methods of connecting the electric lamps in the electric circuits
The electric circuits
The electric circuit is known as a closed and continuous path through which , the electricity will pass making a complete cycle .
The simple electric circuit
|The simple electric circuit consists of the battery , the lamp , and the electric wires .|
The simple electric circuit consists of the battery , the electric wires , and the lamp .
The battery works as a source of the electric current in the electric circuit , It has two poles ( the positive and the negative poles ) , The electric wires are used to connect the battery with the lamp in the electric circuit .
The lamp lights when all the parts of the electric circuit are connected together ( a closed circuit ) , So the electric current passes through the circuit , And the lamp does not light when all the parts of the electric circuit are not connected together ( an open circuit ) , So the electric current does not pass through the circuit .
Methods of connecting the electric lamps in the electric circuit
The electric lamps are connected in the electric circuits by the series connection and the parallel connection .

The series connection
The series connection is a way in which the light bulbs are connected one after another in one route , By increasing the number of the connected light bulbs , The lighting ( The light intensity ) of the bulbs decreases and vice versa .
In the series connection , There is one route for the electric current to pass through the circuit . So , by unscrewing or burning out one bulb , the electric current does not flow .
The parallel connection
The parallel connection is a way which the light bulbs are connected in branching routes . And by increasing the number of the connected light bulbs , the lighting ( The light intensity ) of the bulbs remains as it is .
There are branching routes for the electric current to pass through the circuit . So , by unscrewing one of the lamps , the electric current passes in the other routes , and the lamps in the circuit do not turn off .
All the lamps and the machines in the house are connected in parallel with the main distributer of the energy , So their function is independently .
In the decorative lights that is used in the religious celebrations and the weddings , The lamps are connected in parallel . So , if one or more lamps burn out , the other lamps do not turn off .
