Trimmer capacitors are used to calibrate (trim) the capacitance in a circuit. They are connected in parallel with some other capacitor, and the circuit is calibrated by observation of response to known stimuli. Since trimmer capacitors are often used in RF circuits, it is generally not possible to make measurement of the capacitors out of circuit because parasitic capacitance at RF is not negligible.
Additional question received on April 6th: "I have a 3 terminal trim cap; 2 terminals read continuity, the other not. My question is how do I connect this in a circuit?"
In all probability, the two terminals that read continuity are the same terminal, and are simply provided to give three point mechanical stability when soldered into a circuit. You would connect the two terminals that do not have continuity, using either of the terminals that do have continuity, across the capacitor that needed to be "trimmed".

How do you wire start and run capacitors into an electric motor?
Connect your start capacitor in series with the start winding.Connect the run capacitor in the common terminal and Line 1 of the power supply.
How a trimmer capacitor use?
A trimmer capacitor is a semi-adjustable capacitor placed across a variable tuning capacitor and pre-set to allow the main capacitor to track correctly with another variable capacitor on the same shaft. The adjustment takes out any differences introduced by the connected circuit.
Can you replace a 2-30 trimmer capacitor with a fixed value capacitor?
Yes you can. But the variable one is used so that you can very the frequency and it cant be varied anymore if you use a fixed capacitor.

What will happen if you connect 12volt battery to a 240VOLT capacitor?
If the capacitor is charged then the battery will explode.
How do you connect a targa capacitor to your amplifier?
To connect a Targa capacitor to your amplifier, first ensure the amplifier is turned off and disconnected from power. Connect the positive terminal of the capacitor to the positive power terminal of the amplifier, and the negative terminal of the capacitor to the negative power terminal. Finally, connect the capacitor's ground terminal to a solid ground point on the vehicle. Always double-check your connections and polarity before powering the system back on.

Can blackberry 8900 connect to tv?
No, you would need an alternating capacitor to connect.
How do you connect a capacitor in simulink?
To connect a capacitor in Simulink, you can use the "Capacitor" block found in the Simscape > Electrical > Specialized Power Systems > Elements library. Drag the block into your model and connect its terminals to the appropriate components, such as voltage sources or resistors, to complete the circuit. Ensure that you configure the capacitor's parameters, such as capacitance value, in the block's dialog box for accurate simulation results. Finally, connect necessary measurement blocks to analyze the capacitor's behavior in the circuit.
How to add a capacitor and resistor in parallel?
To add a capacitor and resistor in parallel, simply connect one terminal of the capacitor to one terminal of the resistor, and then connect the other terminal of the capacitor to the other terminal of the resistor. This creates a parallel circuit where both components share the same voltage.
Why connect capacitor to alternator?
To help produce voltage.
Can a non polarized capacitor be connected to a direct current circuit?
Yes, you can connect a polarized capacitor to a direct current. Make sure you get your polarization is correct.A non polarized capacitor can be connected in a DC circuit as well. "Non Polarized" just means it does not matter which side of the capacitor is positive. If you attempt to connect a polarized capacitor in a DC circuit backwards, you will know when the capacitor explodes.
