Alternating currents (AQA A-Level Physics): Flashcards

$\varepsilon = BAN\omega \sin(\omega t)$

Magnetic flux density

EMF is alternating (direction changes over time)

Sinusoidal wave

Vertical line

$V_{\text{rms}} = \frac{V_0}{\sqrt{2}}$

$I_{\text{rms}} = \frac{I_0}{\sqrt{2}}$

$f = \frac{1}{T}$

Highest point of waveform from zero position

230 V
