A device 'X' is connected to an a.c. source. The variation of voltage, current and power in one complete cycle is shown in Fig.
(a) Which curve shows power consumption over a full cycle?
(b) What is the average power consuption over a cycle ?
(c) Identify the device 'X'.

Text Solution

Verified by Experts

A study of given curves in Fig. reveals that
(a) power consumption over a full cycle is represented by curve A.
(b) Average power consumption over a full cycle = Zero , as is clear form curve A.
(c ) The device X may be an inductor (L) or a capacitor (C )or their combination (LC)
