Series & Parallel Circuits (OCR GCSE Physics A (Gateway Science Suite)): Flashcards

All components connected in a single loop

Entire circuit breaks; no components work

Same at every point in the circuit

Amperes (A)

Ammeter

Shared among the components

$V_{total} = V_1 + V_2 + V_3 + ...$

Multiple paths; each component in own branch

Other branches continue to work

Total current divided among branches

$I_{total} = I_1 + I_2 + I_3 + ...$

Same across each branch as power source

$V_{total} = V_1 = V_2 = V_3 = ...$

In series with the component
