Question

An inductor, a resistor and a capacitor are joined
in series with an AC source. As the frequency of
the source is slightly increased from a very low
value, the reactance
(a) of the inductor increases
(b) of the resistor increases
(c) of the capacitor increases
(d) of the circuit increases

Answer 1

Answer:

A. of the inductor increases.

EXPLANATION:-

The reactance of inductor, XL=ωL

The reactance of capacitor,Xc=1/ωC ,

where ω=2πn & n is the frequency of A.C source.

Therefore, reactance of inductor increases.
