Characteristics of a series circuit

Characteristics of a series Circuit 

Series circuit is the simplest form out of the three.
Series circuits have only one path for the flow of electricity or electrons.

In a series circuit, there is only one path of electrons to flow.










The current flow in a series circuit must be the same at any point in a series circuit. This means that if you measure the amount of current at any point in the series circuit, the current must be the same at another point in the circuit. Therefore, if you measure the amount of current to be 2 Amps in a series circuit at  point A, you can assume that the amount of current you will find at all other points in the circuit will be 2 Amps.


Sum of the voltage drops around the circuit must equal the applied voltage in a series circuit. The total voltage or applied voltage should be the sum of all voltage drops. If the voltage drop at point A equals 40 V, point B equals 20 V, and point C equals 60 V, then the applied voltage before crossing any load should be 120 V (40 V + 20 V + 60 V).


Total resistance is equal to the sum of the individual resistors in a series circuit. Just like the sum of voltage drops at each load should equal the applied voltage, resistance should also equal the sum of individual resistors. If the resistance at point A equal 20 Ohms, point B equal 10 Ohms, and point C equal 30 Ohms, then the total resistance should be the sum of all resistors existing in the series circuit which is 60 Ohms.
