Electricity Flashcards
What is the condition that must be met in order for the electricity to flow?
The circuit must be complete, from the battery through to the components and back again.
What is electricity?
The flow of charge around a circuit carrying energy from the power supply to other components
What is voltage?
The push or force of the electricity.
Voltage and current means?
The switch is closed making a complete circuit so current can flow.
NO voltage and NO current means?
Without the cell there is no source of voltage so current cannot flow.
What is the unit of voltage and what is it usually abbreviated to?
The unit is the volt and is abbreviated to V
What is the unit of current and what is it usually abbreviated to?
The ampere (amp) and is abbreviated to A
Voltage but NO current means?
The switch is open so the circuit is broken and current cannot flow.
