Frequency

Written by Jerry Ratzlaff. Posted in Electromagnetics

Frequency is the number of times an alternating current reverses itself in one second.  Expressed in Hertz (Hz), which is one cycle per second.

  • Abbreviated as FREQ

formula

\(f =   \frac { 1 } { T  }  = \frac { N_c } { t  }   \) 

Where:

\(f\) or \(\nu\) (Greek symbol nu) = frequency

\(T\) = period, the time required for one cycle

\(N_c\) = number of cycles

\(t\) = time, seconds

Solve for:

\(T = \frac { 1 } { f }    \)
