AC circuits In this section we come across the formulae the period of a sine wave is equal to 1/f , T= 1/f and that the frequency of a sine wave is equal to 1/T f= 1/T (where f = frequency in Hertz and T = time in seconds). This should be quite straight forward as is it normal division but watch out for the prefixes as for f= 1/T & T= 1/ff = frequency in Hertz and T = time in seconds
