Give expressions for the sine-wave voltage signals having a) 10V peak amplitude and 1kHz frequency
Fist step
Pick Vp and ω. Here Vp = 10, f = 1000 Hz → ω = 2π·1000
Answer (plugged in)?
A: v(t) = 10 · sin(2π · 1000 · t) V

120Vrms and 60Hz frequency 2nd STEP?
Vp = Vrms·√2 = 120·√2 ≈ 169.7056; ω = 2π·60.
