Voltage And Current Flashcards
1
Q
What is current?
A
Current is the flow of electrical charge. It is a measure of the amount of electrons passing a particular point in a circuit per second.
2
Q
What is voltage?
A
Voltage is also known as potential difference because it measures a change in the stored energy of the charge as it moves between one place and another. It is the measure of the amount of electrical energy gained or lost by electric charge as it moves through the circuit.
3
Q
What measures current?
A
An ammeter measures current.
4
Q
What measures voltage?
A
A voltmeter measures potential difference (voltage).
5
Q
What does a multimeter measure?
A
A multimeter measures both current and potential difference (voltage).
