Question

Which of the following curves may represent the reactance of a series LC combination? [DoE]

Answer 1

Answer:

Reactance of capacitor, X

C

=

jωC

1

=

ωC

−j

Reactance of inductor, X

L

=ωL

Since in series combination, net reactance=X

C

+X

L

=j(ωL−

ωC

1

)

So reactance magnitude tends to infinity as frequency tends to 0 as well as infinity
