Series: 1 path all components in a single loop
Parallel: Many paths
Currents: How quickly the electrons more (flow) measured in amps Currents symbol is I
Voltage: How much energy the electrons are carrying, measured in volts Voltage symbol is V
Resistance: Used to slow/resist the flow of electrons (current) measured in ohms Resistance has symbol R
Voltage rule: In series, the voltage is split between components. In parallel, the voltage is the same everywhere (volts V)
Current rule: In series current is the same everywhere. In parallel is split between pathways.
Between resistance and the area of the cross-section of a wire is inversely proportional. When resistance is increased in a circuit, for example by adding more electrical components, the current decreases as a result.
