Q
What 2 things are important for circuits to work?
A
- There must be a COMPLETE circuit
- There must be no SHORT circuits

Q
Current (A) Pic 2
A
- The current flowing through a component in a circuit is measured using an ammeter
- The ammeter must be connected in series with the component

Q
Measuring voltage: Pic 3
A
- Potential difference is measured in Volts (V)
- Potential difference across a component in a circuit is measured using a voltmeter
- The voltmeter must be connected in parallel with the component

Q
What happens when 2 or more components are connected in series?
A
When two or more components are connected in series, the total potential difference of the supply is shared between them. In our example V1 = V2 (if the bulbs have the same resistance).
6
Q
What does adding the voltage across each component in series give the voltage of the power supply?
A
Adding together the voltages across each component connected in series gives the voltage of the power supply. V1 + V2 = V3
