The students are to note that the form factor of a saw-tooth wave has been

calculated as 1.15 whereas for a sine wave the value was 1.11. Since a saw-
tooth wave is stiffer than a sine wave, its form factor is higher than that of a

sine wave.

3.2 SINGLE-PHASE AC CIRCUITS
A resistance, an inductance, and a capacitance are the basic elements of an ac

circuit. These elements are connected in series and parallel combinations to
form an actual circuit. Circuits may include any two or three elements. For

example, we may have one resistance and one inductance connected in series
across an ac supply source. We may have one resistance connected in series
