Series, Parallel and Series/Parallel are the basic circuit resistance configuration types that you may encounter. The first is the easiest of the three: In a Series circuit resistance configuration. Series Circuit Rules
1. Total Resistance is the sum of the individual series resistances
2. Current is the same throughout the series circuit
3. The Sum of the voltage drops equals the voltage rises—Voltage Rises are supply voltages and Voltage drops are the voltages across the resistors.
The supply voltage is divided across series resistors in proportion to their resistance values. A series circuit is therefore called a voltage divider network.
