The voltage as a function of time for the power source oscillating at the given frequency is determined as V = 169.7sin(120πt).
<h3>
Peak voltage</h3>
The peak voltage of the source is calculated as follows;
Vrms = 0.7071V₀
120 = 0.7071V₀
V₀ = 120/0.7071
V₀ = 169.7 V
<h3>Angular frequency of the wave</h3>
ω = 2πf
where;
f is frequency = 60 Hz
ω = 2π x 60
ω = 120π rad/s
<h3>Voltage equation as function of time</h3>
V = V₀sin(ωt)
V = 169.7sin(120πt)
