The graphs given below depict the dependence of two reactive impedances $X_1$ and $X_2$ on the frequency of the alternating e.m.f. applied individually to them. We can then say that

• A
  $X_1$ is an inductor and $X_2$ is a capacitor
• B
  $X_1$ is a resistor and $X_2$ is a capacitor
• C
  $X_1$ is a capacitor and $X_2$ is an inductor
• D
  $X_1$ is an inductor and $X_2$ is a resistor
