Current, voltage and resistance

• 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.
