Key Stage 2
Meaning
Voltage is how much push electricity has.
About Voltage
- The bigger the voltage the more push the electricity has to go around the circuit.
- Adding another cell to the circuit in series will increase the voltage.
- With a bigger voltage a lamp will be brighter and a buzzer will be louder.
A series circuit with one cell and one bulb. | A bulb will be brighter if the voltage is higher. |
Key Stage 3
Meaning
Potential Difference is how much energy is transferred by a current.
