Sinusoidal waveforms
What Sinusoidal waveforms means in Physics A-Level, as defined for AQA.
Definition of Sinusoidal waveforms
Check what you remember
Read the wording for your board, then hide it and explain Sinusoidal waveforms in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The relationships V_rms = V₀/√2 and I_rms = I₀/√2 apply only to these; other waveforms need their own rms calculation.
