U se the formula for instantaneous sine voltage and current to sketch an accurate sinusoidal waveform. D efine the period of a waveform. C ite the units of measure for the period of a waveform. D efine the frequency of a waveform.
C ite the units of measure for the frequency of a waveform.
C onvert between values for the period and frequency of a waveform. The period of a waveform is the time required for completing one full cycle. The frequency of a waveform is the number of cycles that is completed each second. This example shows four cycles per second, or a waveform that has a frequency of 4 Hz . E A certain sine waveform has a frequency of 100 Hz.
