How do you determine the size of acapacitor in a rectifier circuit?
ANSWER In rectifiers for power supplies, the capacitor size is determined by the allowable ripple on the output. This can be determined by the rate at which the capacitor is drained. Specifically, this rate is the current drawn from the capacitor. Assume a half wave rectifier made from four diodes. For part of the cycle, the output current is supplied by the rectifier diode. This is also when the capacitor is charged. While the rectifier is not supplying current -- when the input waveform has dropped below the output voltage -- the capacitor must supply the current. Then, as the input waveform rises above the capacitor voltage, the rectifier supplies the current to charge the capacitor and the output circuit.
Can you by-pass a capacitor in an electric motor?
You can not by-pass the capacitor in an electric motor. Most are capacitor-start motors which require the capacitor to be operational in order to start. If the capacitor is not working then it will need to be replaced.
What are the three factors that determine the charge of a capacitor?
If you mean the capacity of the capacitor then, Factors are:- Area of of overlap of the plates Separation of the plates How good is the insulating material between the plates (the dielectric) If you mean how large a charge can be stored then, Factors are:- The capacitance of the capacitor (C). The applied voltage (V). Charge Q =CxV V cannot exceed the dielectric's breakdown voltage.

Why is there a C in the equation for a discharging capacitor?
The C represents the capacitance (in farads) of the capacitor. It is a measure of how much charge a capacitor can hold. This is needed to know how much energy the capacitor is holding.
What two facctors determine the capacitive reactance of a capacitor?
The two factors that determine the capacitive reactance of a capacitor are the frequency of the AC voltage applied to the capacitor and the capacitance value of the capacitor. At higher frequencies and with larger capacitance values, the capacitive reactance decreases.
How can one determine the process of finding the charge on a capacitor?
To determine the charge on a capacitor, you can use the formula Q CV, where Q is the charge, C is the capacitance of the capacitor, and V is the voltage across the capacitor. By measuring the capacitance and voltage, you can calculate the charge on the capacitor using this formula.
How do you fix the run capacitor on a ceiling fan?
Be certain to observe the exact same polarity as the old one. A capacitor does have plus and minus leads. Should an old defective ceiling fan transformer be replaced by a capacitor?
How do you determine whether the capacitor is in workinfg condition?
Remember that a working capacitor can't conduct current through it. A capacitorthat's NOT in working condition has typically failed because the dielectric has beenpunctured, resulting in a conductive path between the 'plates'. Any DC conductivitythrough the capacitor indicates that the component has failed. DC conductivity iseasy to spot with an ohmmeter.
When do you replace your ignition switch?
When you determine that it is defective.
How do you change a bad capacitor in an air conditioner?
Locate the defective capacitor, short the terminals to ground to release any stored energy and prevent shock, remove the old capacitor then install the new capacitor wired as the old one was and secure it in the bracket that held the old one - done.
What method is used to determine defective concrete?
sounding technique
How can one determine the potential difference across a capacitor?
The potential difference across a capacitor can be determined by using the formula V Q/C, where V is the potential difference, Q is the charge stored on the capacitor, and C is the capacitance of the capacitor.
How can I test an AC capacitor to determine if it is functioning properly?
To test an AC capacitor, you can use a multimeter set to the capacitance setting. Disconnect the capacitor from the circuit, discharge it, and then connect the multimeter leads to the capacitor terminals. The reading should be close to the labeled capacitance value. If the reading is significantly lower or higher, the capacitor may be faulty.
What factors determine the resistance of a capacitor and how does it affect the performance of the capacitor in an electronic circuit?
The resistance of a capacitor is determined by its construction and materials used. Higher resistance can lead to slower charging and discharging of the capacitor, affecting the performance of the capacitor in an electronic circuit by potentially causing delays in signal processing or affecting the overall efficiency of the circuit.
How to test an AC capacitor with a digital multimeter?
To test an AC capacitor with a digital multimeter, set the multimeter to the capacitance setting. Disconnect the capacitor from the circuit and discharge it. Connect the multimeter leads to the capacitor terminals and read the capacitance value displayed on the multimeter screen. Compare this value to the rated capacitance of the capacitor to determine if it is functioning properly.
What two factors determine the capacitive reactance of a capacitor?
The two factors that determine the capacitive reactance of a capacitor are the frequency of the alternating current passing through the capacitor and the capacitance value of the capacitor. Capacitive reactance (Xc) is inversely proportional to the frequency (f) and directly proportional to the capacitance (C), as calculated using the formula Xc = 1 / (2πfC).
