GCSE PHYSICS- ELECTRISITY

1. Series

   • Current is the same across all of the components
   • Voltage is shared across all of the components

2. Parallel

   • Current is shared between all of the components
   • Voltage is the same across all of the components

3. Measuring Voltage and current

   • Measuring Voltage
     • A voltmeter is used to measure Voltage
       • A voltmeter has to be set up in parallel to measure the Potential difference of a bulb
   • Measuring Current
     • A ammeter is used to measure current
       • An ammeter has to be connected in series to measure the Amps of a bulb or other electrical components

4. Components

   • Bulb (lamp)
   • Diode
   • Ammeter
   • Resistor
   • LED (Light emitting diode)
   • Voltmeter
   • Cell
   • Battery
   • Variable resistor
   • Switch
   • Fuze
