What is the effect on the magnitude of pure reactance when it is converted to susceptance?

  1. It is unchanged
  2. The sign is reversed
  3. It is shifted by 90 degrees
  4. It is replaced by its reciprocalالإجابة الصحيحة

الشرح

For an element that is purely reactive, susceptance is the negative reciprocal of the reactance, so a large reactance becomes a small susceptance and vice versa. The question asks only about magnitude, and the magnitude is inverted; the sign reversal is a separate consequence of the same relationship.
