JEE Main 2023 — Alternating Current Question with Solution

JEE Main 2023 (11 Apr Shift 1)

Question

As per the given graph, choose the correct representation for curve A and curve B
{Where XC= Reactance of pure capacitive circuit connected with A.C. source
XL= Reactance of pure inductive circuit connected with A.C. source
R= Impedance of pure resistive circuit connected with A.C. source
Z= Impedance of the LCR series circuit }

Choose an option

Show full solutionCorrect option: D
Correct answer
DA=XC,B=XL

Step-by-step explanation

The formula to calculate the inductive reactance is

XL=ωL   ...1

The formula to calculate capacitive reactance is

XC=1ωC   ...2

As can be seen from equation (1), the inductive reactance varies directly with the frequency and equation (2) indicates that capacitive reactance varies inversely with the frequency.

Hence, curve A represents the capacitive reactance and curve B represents the inductive reactance.
