Series and Parallel Circuits
- Only one pathway the current can go
- The total resistance is the sum of all the individual resistors or components
- The total potential difference of the cells is the sum of the individual cells
- The potential difference of the supply is shared between the components
- The current is the same through each component.

Series and Parallel Circuits:
- The potential difference across each component is the same
- The current is different in different branches of the circuit
- The total current through the whole circuit is the sum of the current through the separate components.
- The higher the resistance, the lower the current.

Resistance, Current and Potential Difference
As you increase the potential difference, the current increases too.
- WHEN TEMPERATURE IS CONSTANT
- ACROSS A FIXED RESISTOR
The graph is directly proportional.
If the battery is flipped, there are negative readings at the voltmeter.
