Current, Potential Difference & Resistance (AQA GCSE Physics Combined Science): Flashcards

1 joule of energy per coulomb of charge

In parallel

Shared between components

Same across each component

Two or more cells connected together

Coulombs (C)

1 coulomb of charge flowing per second

$Q = I \times t$

$E = Q \times V$

$R = \frac{V}{I}$

P.D. needed to drive current through component

Same all the way around

Ammeter

Negative terminal to positive terminal

Splits in branches, adds to total
