Why connect a 100 Ohm resistor to the two terminals of a capacitor If the voltmeter doesn't turn to zero would be better to use a larger resistor?
We can guess that the resistor is used for discharging the capacitor's plates. Generally we short the two terminals on a capacitor to discharge it fully. A resistor will take more time to do this than shorting-out the terminals: the higher the resistance, the longer the time that will be taken to discharge a capacitor fully.
Why do you connect a diode in parallel to a capacitor?
1. bec the capacitor not allow the current to pass through it after it has charged & it charged in no time ex:(10^-4 second). 2. because it is necessary to avoid wrong polarity by shorting the terminals of the capacitor and tripping the fuse.
Why does capacitor block dc?
A physical capacitor is made of two conducting plates arranged face-to-face, with vacuum or an insulating material between them. So the capacitor is actually an 'open' circuit ... there's no continuous conducting path through it, and if you connect it to the terminals of a battery, no current flows through it. It performs its job completely by means of the electrostatic forces of attraction or repulsion between charges on the two plates, but there's never actually any flow of electrons across the space between the plates. (If there is, then the 'dielectric' is punctured, and you need a new capacitor.)
How do you connect a trimmer capacitor?
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".

Why do you connect a capacitor with an Ac motor?
The capacitor is used to create a second phase from the single phase power source and it is the interaction between these two phases that causes the motor to turn.
What will happen if you connect 12volt battery to a 240VOLT capacitor?
If the capacitor is charged then the battery will explode.
What is the function of a capacitor's leads?
To connect it to the circuit.
Can blackberry 8900 connect to tv?
No, you would need an alternating capacitor to connect.
How can two 4v lamps be lit up by two 2v cells?
-- Connect the cells in series. The two terminals of their series combination present a potential difference of 4 volts. -- Connect both lamps in parallel between the terminals of the series-connected cells.
How do you connect a single phase capacitor start induction motor forward?
This is for a single voltage motor. If you consider the forward rotation as counter clockwise (CCW) when looking at the motor from the end opposite the drive end, then the connections will be, L1 - terminals 1 and 8, L2 - terminals 4 and 5. To reverse the rotation (CW), then the connections will be, L1 - terminals 1 and 5, L2 - 4 and 8.
Why connect capacitor to alternator?
To help produce voltage.
