Question

21. An a.c. of frequency f is flowing in a circuit
containing only an ideal choke coil of inductance L.
If V, and in represent peak values of the voltage
and the current respectively, the average power
given by the source to the choke coil is equal to
(1) 30 V
(2) 562 (27fL)
L
(3) Zero
(4) Vo (27UfL)​

Answer 1

ANSWER:

Zero

step-by-step explanation:

For a clock coil R >>WL

Power factor cos teta =R/WL =0

Average power = Veff .leff. cos teta

Average power =0

Therefore

Pav =0

Answer 2

Answer:

Zero
