Flow of electric charge (e.g. electrons) around the circuit
Total Charge Through a Circuit Depends on Current and Time
Current is the rate of flow of charge. In metals, the current is caused by a flow of electrons. The charge that has passed a point is given by the formula: charge = current x time
The current flowing through a component depends on the potential difference across it and the resistance of the component
Resistance
Anything that slows the flow down
Electrons in circuits actually move from -ve to +ve, but conventionally current is drawn flowing from +ve to -ve
Generally, the higher the potential difference across a given component, the higher the current will be. The greater the resistance of a component, the smaller the current that flows
