Resistors in Series

Resistors are connected in series when they are daisy chained together in a single line resulting in a common current flowing through them. Resistors in series can be replaced by one single equivalent resistor. All resistors obey the same basic rules as defined by Ohm’s Law and Kirchoff’s Circuit Laws.

Resistors in series have a common current. The current that flows through one resistor must also flow through the others as it can only take one path. The total resistance of the circuit must be equal to the sum of all the individual resistors added together. Series resistor networks can also be thought of as voltage dividers. A series resistor circuit having N resistive components will have N different voltages across it.
