Frequency

Written by Jerry Ratzlaff on . 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:

\(T = \frac { 1 } { f }    \)
