Current, Potential Difference & Resistance (OCR GCSE Physics A (Gateway Science Suite)): Flashcards

1 joule of energy transferred per coulomb of charge

In parallel

P.D. is shared

The same for each component

Two or more cells connected together

Coulombs (C)

1 coulomb of charge flowing per second

$Q = I \times t$

$E = Q \times V$

P.D. required to drive current through a component

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

From negative terminal to positive terminal

Same all the way around

Ammeter

Splits, then adds up to total current
