Capacitive reactance is more when
A. capacitance is less and frequency of supply is less
B. capacitance is less and frequency of supply is more
C. capacitance is more and frequency of supply is less
D. capacitance is more and frequency of supply is more
Explanatory answer:
We know capacitive reactance reactance, Xc = 1 / 2ΠFC
Xc is inversely proportional to F and C.
Therefore Xc increases as frequency and capacitance decreases,hence the suitable answer is option A
