Circuits and Electricity

HideShow resource information

Current is the rate of flow of charge around a circuit. Current will only flow through a component if there is a voltage across that component.

Voltage is the driving force that pushes the current around.

Resistance is anything in the circuit which slows the flow down.The more components to the circuit, there will overall be a higher resistance.

·         When you increase the voltage- then more current will flow.

·         If you increase the resistance- then the less current will flow.

Ammeter- Measures Current

·         Must be placed in series anywhere in the
