If two equal-value capacitors are connected in parallel, what is their total capacitance?

A
Answer
Transmitters, receivers, and measurements
Type
A
Twice the value of one capacitor
B
The value of one capacitor divided by 4
C
The value of one capacitor times 4
D
Half the value of either capacitor

Answer Notes

When capacitors are connected in parallel, their individual capacitances add together directly. The formula for this arrangement is simply C_total = C1 + C2 + ... + Cn. If you connect two capacitors of equal value in parallel, you are essentially doubling the total surface area of the conductive plates capable of storing an electrical charge. Consequently, the total capacitance becomes exactly twice the value of one of the individual capacitors. This principle acts oppositely to resistors in parallel, where total resistance decreases. Options suggesting the value is halved or divided by four are incorrect because they describe the behavior of capacitors wired in series.
