- Here are the basic definitions of current, voltage and resistance:
- CURRENT - is the flow of electrons round the circuit.
- VOLTAGE - is the driving force that pushes the current round.
- RESISTANCE - is anything in the circuit that slows the flow down.
- There is a relationship between these three which is summarised as OHM'S LAW:
- V=IR
- voltage=Current x Resistance
- So if you increase the voltage - then more current will flow, if the resistance is constant.
- If you increase the resistance - then lass current will flow if voltage remains constant.
