Potential Difference Flashcards

All 4 cards in this deck

What is potential difference (voltage)?

The energy transferred per unit charge passed; measured in volts (V).

What is 1 volt equal to in terms of joules and coulombs?

1 volt = 1 joule per coulomb (1 V = 1 J/C).

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

In parallel with the component (across it).

What is the equation linking energy transferred, charge and potential difference?

energy transferred (J) = charge moved (C) × potential difference (V), E=Q×VE = Q \times V.
