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 of the [2017]

(a) inductor increases

(b) resistor increases

(c) capacitor increases

(d) circuit increases​

Answer 1

Answer:

#follow me

Explanation:

option b the resistor increases

Answer 2

An inductor, a resistance 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 is (a) inductor increases

Therefore option (a) is correct

Explanation:

The inducer reactance is given by,

$X_{L}=\omega L$

And The condenser reactance is given by,

$X_{C}=\frac{1}{\omega C}$

Where  $\omega=2 \pi f$

Impedance is expressed in ohms, and may include resistance ( R ), inductive ( XL ), and capacitive ( XC ) reactance

Here,

Where f is source frequency.

So, if f increases, it ω increases as well.

Therefore $X_L$ is going to increase and $X_C$ is going to be going down.
