Question 1
An AC generator produces an output described by v(t) = 250sin(ωt + 30°). Calculate the frequency, period, and RMS voltage.
💡 Hint: Look closely at the amplitude and use the relationship between frequency and period.
Question 2
Consider a waveform represented as v(t) = 400cos(500t - 60°). Find the peak voltage, phase angle, and express it in sine form.
💡 Hint: Use trigonometrical identities to switch from cosine to sine.
