Capacitors in series are like resistors in parallel, the total capacitance is the inverse of the sum of the inverses.
CSERIES = 1 / Summation1toN (1 / CN)
For this question ...
1 / 12 = 1 / 30 + 1 / x
1 / 12 - 1 / 30 = 1 / x
0.05 = 1 / x
x = 20

What does NF on a capacitor mean?
While it is possible that the company producing the capacitor is using the NF as an identification tool, usually we would expect nF to specify the capacitance or value of the capacitor. For example, a capacitor with the value of 10nF ought to have a capacitance of about 10 nano Farads. This is equivalent to 10*10-9 Farads.
What is the difference between capacitor and capacitance?
A capacitor is a device that stores an electrical charge, or if you prefer- resists any change in voltage applied to it. Capacitance is a measure of the size or ability of a capacitor to do that. This is the Farad
Function of dielectric in a capacitor?
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
Why does capacitance increase when the distance between the plates of a capacitor is increased?
you have it reversed. capacitance increases with decrease in distance of plates.
What is the function of fixed capacitor?
A fixed capacitor has a fixed capacitance (within certain limits influenced by aging). So it can fulfill any function that a (variable) capacitor fulfills, beside changing its capacitance easily (e. g. by turning a wheel).
What is the total capacitance of three 30 micro-farad capacitors connected in parallel?
The equivalent capacitance of a 30uF capacitor in parallel with a 20uF capacitor is 50uF.
How are the terms capacitor and capacitance related?
Capacitor is the name of the device and capacitance is a measure of farads in the capacitor. Capacitance is the capacity for storing charge in the capacitor as measured in farads, micro farads or millifarads.
What will the affect of capacitance of a capacitor when a conductor is placed between a capacitor?
capacitance will tend to zero
What means by the name capacitance of a capacitor?
The capacitor is an electronic device. Capacitance is the energy stored within this device.

What is a capacitor analyzer designed to read?
Capacitor voltage
What is the ratio of capacitance of capacitors?
ratio of capacitance of capacitor is given by charge\potential
What is the relation between the ac voltage frequency and the capacitor impedance?
A capacitor impedance is equivalent to 1/jwC, where j = i = imaginary number, w = frequency, and C = capacitance in Farads.
What two facctors determine the capacitive reactance of a capacitor?
The reactance of a capacitor is a function of -- the capacitance of the capacitor -- the frequency of the voltage across the capacitor
What is the difference betbeen capacitor and condensor?
A: Both nomenclature are indicator of capacitance it can be used both ways. However the predominate usage is capacitor since it resemble capacitance
Capacitance is the property of an electrical circuit that?
A capacitor resists a change in voltage, proportional to current, and inversely proportional to capacitance. The equation of a capacitor is dv/dt = i/c.
