Reactance and Impedance

Electricity and Magnetism Level 2

The above are three different RLC series circuits, in each of which the resistance of the resistor is \(R,\) the self-inductance of the inductor is \(L,\) and the capacitance of the capacitor is \(C,\) if applicable. If the RMS(root mean square) values of the current flowing in circuits [A] and circuit [B] are the same, then which of the following statements is correct?

a) The inductive reactance of the inductor is the same as the capacitive reactance of the capacitor.
b) The impedance of circuit [C] is \(R.\)
c) The RMS value of the current flowing in circuit [C] is greater than that flowing in circuit [B].
