Series circuit means the connection of two or more parts are connected one after an other.
Rules in a series circuit
- Voltages in Series circuits add up: The sum of all voltage sources is equal to the sum of all voltage consumers. For example a 9 V Battery powers 2 equal lamps which are connected in series: The two lamps share the voltage in equal parts of 4.5 V each.
- Current through all parts of the series circuit is equal at any point.

Voltage Divider
2 Resistors which are connected in series share the voltage according to their resistance values.
