## Frequency Units

What are the base SI units for frequency?

Expand Hint
The SI unit for frequency is hertz (Hz).
Hint 2
For a sinusoidal voltage or current of frequency:
$$f=\frac{1}{T}$$$where $$T$$ is the period. Frequency is the number of repeating event occurrences per unit of time. The SI units for frequency is hertz (Hz). For a sinusoidal voltage or current of frequency: $$f=\frac{1}{T}$$$
where $$T$$ is the period in seconds.
$$1\:Hz=\frac{1}{sec}=sec^{-1}$$$$$sec^{-1}$$$
