has no effect on the capacitive reactance
doubles the amount of capacitive reactance
multiplies the capacitive reactance by 7
cuts the capacitive reactance in half E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is: A. has no effect on the capacitive reactance.
Capacitive reactance is inversely proportional to the frequency of the applied voltage. Doubling the operating voltage does not change the frequency of the applied voltage, so it has no effect on the capacitive reactance.
Option B is incorrect because doubling the operating voltage doubles the capacitive reactance.
Option C is incorrect because doubling the operating voltage does not multiply the capacitive reactance by 7.
Option D is incorrect because doubling the operating voltage does not cut the capacitive reactance in half.
Option E is incorrect because doubling the operating voltage does have an effect on the capacitive reactance, but it is not one of the options listed.
