 Impedance Triangle

The phasor diagram of a R-L series circuit is shown in Fig. (a). Dividing each side of the phasor diagram by the same factor I, we get a triangle whose sides represent R, XL and Z. Such a triangle is known as impedance triangle  See Fig. (b). Just as in Fig. (a), the impedance triangle is also a right-angled triangle

                                                                                        figure                 

Impedance triangle is a useful concept in a.c. circuits as it enables us to calculate

Therefore, it is always profitable to draw the impedance triangle while analysing an a.c. circuit.
