[amp_mcq option1=”equal to the sun of the individual capacitive-reactance values” option2=”equal to the sum of the individual capacitance values” option3=”equal to the source voltage divided by total current” option4=”less than the value of the smallest capacitor E. None of the above” correct=”option2″]
The correct answer is: B. equal to the sum of the individual capacitance values.
A series capacitor circuit is a circuit in which two or more capacitors are connected in series. The total capacitance of a series capacitor circuit is equal to the sum of the individual capacitance values. This is because the capacitors in a series circuit share the same current, and the total charge stored in the circuit is equal to the sum of the charges stored in each capacitor.
Option A is incorrect because the capacitive reactance of a capacitor is inversely proportional to its capacitance. Therefore, the sum of the individual capacitive-reactance values will be less than the capacitive reactance of the largest capacitor.
Option C is incorrect because the source voltage divided by total current is equal to the impedance of the circuit. The impedance of a series capacitor circuit is equal to the sum of the individual impedance values, which are equal to the capacitive reactance values.
Option D is incorrect because the total capacitance of a series capacitor circuit is always greater than the value of the smallest capacitor. This is because the capacitors in a series circuit share the same current, and the total charge stored in the circuit is equal to the sum of the charges stored in each capacitor.
Option E is incorrect because the total capacitance of a series capacitor circuit is always equal to the sum of the individual capacitance values.
