Question

As per the given graph, choose the correct representation for curve A and curve B {Where X C = Reactance of pure capacitive circuit connected with A.C. source X L = 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 L C R series circuit }, A = X C , B = R, A = X L , B = R, A = X L , B = Z, A = X C , B = X L

The formula to calculate the inductive reactance is X L = ω L . . . 1 The formula to calculate capacitive reactance is X C = 1 ω C . . . 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.
