Series Circuits
A circuit can be set up as a series circuit. A series circuit will be set up as one continuous loop.
Series circuits
- In a series circuit, components are added in a loop.
- There are no branches in a series circuit.
- For the components to work, the circuit must be complete.
Bulbs in a series circuit
- The more bulbs in a series circuit the dimmer they will be.
- The more cells the brighter the bulbs will be.
- If one of two or more bulbs breaks, the circuit breaks.
- So current will not flow.

Current in series circuits
- Current in a series circuit remains the same everywhere in the circuit.
Potential difference in series
- Potential difference is shared with all the components in the series circuit.
- The total potential difference of the components will equal that of the cell or battery.
Test yourself on Series Circuits
What happens if a component breaks in a series circuit?
