A capacitance meter is a piece of electronic test equipment used to measure capacitors. Depending on the sophistication of the meter, it may simply display the capacitance or it may also measure a number of other parameters such as leakage, equivalent series resistance, and inductance.

What is the application of schering bridge?
to measure unknown capacitance
Definition of a capacitance in mosfet?
Capacitance in mosfet is of three types: gate capacitance diffusion capacitance routing capacitance Gate capacitance: limits the speed of the device t which it can be operated Diffusion capacitance: It is the capacitance due to charge carriers between drain and source. Routing capacitance: It is the capacitance of the metal which is deposited on the top of oxide layer.
What kind of supply is given to schering's bridge?
schering's bridge is used to measure capacitance and dissipation factor of a capacitor. AC voltage is given to the terminals of bridge and bridge is balanced by varying resistance and capacitance in the opposite arm.
How do you measure the capacitance of 3 phase capacitor in active line voltage of 3 phase circuit?
You measure the capacitance of a capacitor in an active circuit by observing the voltage across it and the current through it. That gives you, by Ohm's law, the impedance of the capacitor. Plug that in the the equation for capacitive reactance, and you get capacitance. Note: There is no such thing as a three phase capacitor. A capacitor is a two terminal device that resists a change in voltage inversely proportional to its capacitance. You connect one capacitor to one phase. If you have a "three phase capacitor", then you are talking about three capacitors. Deal with each one separately.
How do you calculate the stray capacitance?

What is the application of schering bridge?
to measure unknown capacitance
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 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
What is the unit of measure for capacitance?
The Farad is used to measure capacitance. Most small electronic capacitors are in microFarads(uF) or picoFarads (pF). The unit is name after Michael Faraday, the English chemist and physicist.
Is it possible to measure capacitance using only one 555 timer?
yes, it is possible to measure capacitance using only one 555 timer for it's monostable operation. When the output is high time is given by the equation t=1.1RC. From the output pulse measuring t(high) and then by measuring R we can calculate the capacitance.
How do you measure inductance?
You can use a LCR (Inductance, Capacitance, Resistance) meter if you can find one.
How do you measure capacitance using fluke 87?

How do you measure capacitor's value?
The equation of a capacitor is dv/dt = i/c. The capacitor resists a change in voltage, inversely proportional to its capacitance. One way to measure capacitance is to plot voltage and current through a resistor following a voltage step change. The slope at any point will give you the answer. Another way is to measure the resonant frequency in circuit with an inductor. Another way is with a Maxwell bridge. See "How do you draw the vector diagram of maxwell's capacitance bridge?"

What are the methods to find capacitance of a capacitor?
You could measure it with a Capacitance meter. Or you could use the formula:In a parallel plate capacitor, capacitance is directly proportional to the surface area of the conductor plates and inversely proportional to the separation distance between the plates. If the charges on the plates are +q and −q, and V gives the voltage between the plates, then the capacitance C is given byFor further info on the total value of capacitance in series or parallel, Google it.
How many kelvins are there in 97.4 Farads?
A farad is the SI unit of capacitance, Kelvin is a measure of temperature. The two measure different things and there is no direct conversion from one to the other.
