Definitions (AQA A-Level Physics): Flashcards

$C = \frac{Q}{V}$

Opposes supplied PD and limits current

$E = \frac{F}{q}$

Induced emf equals rate of change of flux linkage

Induced current opposes change that caused it

$\Phi = B \times A$

$\tau = RC$

24 hours

$v = \sqrt{\frac{2GM}{r}}$

$T^2 \propto r^3$
