DETAILED ANSWERS
Two capacitors, a 20 µF and a 30 µF, are connected in parallel to a 400 Hz source.
The total capacitive reactance is
a) 7.96 ohms
b) 33.16 ohms
c) 221.04 ohms
d) 53.05 ohms -correct-answer-Answer: a) 7.96 ohms
The formula for calculating capacitive reactance is XC = 1/(2πfC), where:
XC: is the capacitive reactance, measured in ohms
f: is the frequency of the alternating current in hertz
C: is the capacitance of the capacitor in farads
The total reactance of capacitors connected in series can be calculated using the
equation XCT = XC1 + XC2 + XC3 + ... + XCN
