A sinusoidal alternating
voltage has a peak value of 12 V and a frequency of 50 Hz.
Calculate its time period.
Write an equation that
would allow you to work out the instantaneous voltages for a
time, t, after the voltage went through the 0 point.
Include numerical values in the terms.
Use your equation to
work out instantaneous values for the voltage at these
times. Show your working out.
