A voltage can be either a DC voltage where frequency is
zero (absent) OR can be an AC voltage where frequency is
present. If potential between two points in an
Electrical / electronic circuit changes ferquently from
zero to positive, positive to zero, zero to negative and
back to zero taking any shape like sinusoidal, square,
triangular etc., then frequency can be defined number of
cycles it completes from zero-positive-zero-negative-zero
in one second. I.e. cycles/second. If potential between
two points doesn't change but remains constant for a period
of time, frequency is absent & it is called DC potential or
DC Voltage.
Summary : Frequency defines value of voltage changes per
second.
