You have a sinusoidal waveform described by v(t) = 400sin(200πt + 30°). Calculate its frequency, period, amplitude, and phase angle. Discuss the significance of these parameters in AC circuit analysis.
💡 Hint: Be sure to use the formulas for each parameter accordingly.
A capacitor and inductor are connected to a sinusoidal source described by v(t) = 230cos(60t). What are the frequency and period? How does the phase-angle affect the current through the inductor?
💡 Hint: Find the parameters first and then relate them to inductive reactance.
