Potential Difference Flashcards

All 5 cards in this deck

What is potential difference (voltage)?

The energy transferred per unit charge passed.

What is 1 volt equal to in other units?

1 joule per coulomb.

How must a voltmeter be connected to measure the potential difference across a component?

In parallel with the component (connected across it).

True or false? A voltmeter is connected in series with the component whose potential difference is being measured.

False. A voltmeter is connected in parallel with (across) the component.

What quantity does a voltmeter measure, and in what unit?

Potential difference (voltage), in volts (V).
