The purely resistive system is said to have a unity power factor. Purely Inductive Load A good example of such a system is an induction motor. The circuit, the curves, and the phasor diagram for the system are shown in Figure 3 below. Figure 3. Purely Inductive Load Circuit, Phaso...
(d) Draw the phasor diagram for the device X. View Solution Q3 A device 'X' is connected to an ac sources V=V0sinωt. The variation of voltage, current and power in one cycle is in the following graph: (a) Identify the device 'X'.(b) Which of the curves A, B and C repre...
