In a series circuit, the electrical components are connected in a multiple loopsingle loop, one after the other. The electric charge in a series circuit can only flow in one directiontwo directionmultiple directions.

 

If the circuit is broken or disturbed at any point in the loop, the current can flow current cannot flow  through the circuit, and hence electric appliances linked to it will not functionwill function.

 

1. Let the resistances of three resistors be \(R_1\), \(R_2\) and \(R_3\), be connected in seriesparallel along with a battery, a plug key and an voltmeterammetergalvanometer.

 

2. Let '\(I\)' be the not equal to the reciprocal of the effective equal to the reciprocal of the effective  current flowing through the circuit.

 

3. Connect the voltmetergalvanometerammeter in between the resistors \(R_1\) and \(R_2\) and note the reading of ammeter.

 

4. Now connect the galvanometervoltmeterammeter in between the resistors \(R_2\) and \(R_3\).

 

5. Again note the current value.

 

It is deduced that the current '\(I\)' remains variesconstant throughout the series circuit. In other words, the current in every point or junction of the circuit is the lessersamehigher.
