For a periodic waveform, defined the following.1, frequency, 2, period 3, root mean square value

Here are the definitions for the terms related to a periodic waveform:

1. Frequency:

   • Frequency is the number of cycles or oscillations that a periodic waveform completes in one second. It measures how often a repeating event occurs. The standard unit for frequency is the hertz (Hz), where $1 \text{ Hz}$ equals one cycle per second.

2. Period:

   • The period is the time it takes for a periodic waveform to complete one full cycle. It is the reciprocal of frequency. The standard unit for period is the second (s).
   • The relationship between period ($T$) and frequency ($f$) is given by $T = \frac{1}{f}$.

3. Root Mean Square (RMS) value:

   • The root mean square (RMS) value of a periodic waveform (like an alternating current or voltage) is the effective value that would produce the same average power dissipation in a resistive load as a DC current or voltage of the same magnitude. For a sinusoidal waveform, the RMS value is $\frac{1}{\sqrt{2}}$ times its peak value.
