Series Circuit Diagram With Resistor. In such circuits the voltage across each resistor is different. Then series resistor networks can also be thought of as voltage dividers and a series resistor circuit having n resistive components will have n different voltages across it while maintaining a common current.
In the three resistor example circuit below we know that we have 9 volts between points 1 and 4 which is the amount of electromotive force driving the current through the series combination of r 1 r 2 and r 3. The construction of a series circuit is simpler. A series circuit is characterized as a circuit in which the same amount of current passes through all the resistors.
The current through the circuit is the same for each resistor in a series circuit and is equal to the applied voltage divided by the equivalent resistance.

As shown in the above diagram n resistors are connected in series so the same current passes through every resistor and the total resistance must be equal to the sum of all the resistors in the series. By using ohm s law either the voltage current or resistance of any series connected circuit can easily be found and resistor of a series circuit can be interchanged without. A circuit is said to be connected in series when the same amount of current flows through the resistors.
