Extra exam question E5B05
Subelement E5, ELECTRICAL PRINCIPLES· Group E5B
What is the effect on the magnitude of pure reactance when it is converted to susceptance?
- A.It is unchanged
- B.The sign is reversed
- C.It is shifted by 90 degrees
- D.It is replaced by its reciprocal (correct answer)
WhyConverting a pure reactance to susceptance replaces it with its reciprocal. Converting a pure reactance to its equivalent susceptance replaces it with its reciprocal, the same inverse relationship that connects impedance to admittance generally, answer D. The magnitude isn't simply left unchanged, having only its sign reversed, or shifted by a fixed 90 degrees, those don't describe the actual reactance-to-susceptance conversion.
