Resistors in Series

When you have two resistors in a circuit and they are tied together so that current flows through one of them and then the other, they are said to be in series.

The resistors R1 and R2 are in series. The current I flows through both of them.

Notice in the schematic above that the resistors are in line, one after the other. Since resistors work by reducing the current that flows in a circuit, it follows that two resistors reduce the current flowing in the circuit even more.

Think of light filters stacked up in a row. The first filter cuts the light by a certain percentage. That reduced light hits the second filter, which reduces the total light by an additional percentage.

Likewise, when current goes through two resistors in series, the total current is reduced because the total resistance has gone up.
