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.
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.
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.
Flying capacitor multilevel inverter?
what is flying capacitor
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 reactance of a capacitor is a function of -- the capacitance of the capacitor -- the frequency of the voltage across the capacitor
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?
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
What two factors determine the capacitive reactance of a capacitor?
capacitive reactance is inversely proportional to the capacitance of the capacitor and frequency of the AC line reactance (in ohms) = 1/(capacitance * frequency)
How can I determine the capacitance of an unknown capacitor?
There are several multimeters which allow you to find out the pF of a capacitor, at least paper and ceramic types. You may want to look up YouTube videos that show you how to use a multimeter to determine the capacitance. Again, it is dependent on the capacitor we are talking about. Sometimes they are rated and have a data sheet, sometimes a test bench may be required to perform things.
Does a magnetic fIEld have an effect on a capacitor placed in between the plates?
Does a magnetic field have an effect on a capacitor when it is placed between the plates? Yes, a magnetic field between the plates of a capacitor would have some effect. Without more information it is difficult to determine how much.
What is the value of capacitor for 1hp ac motor?
The value of the capacitor for a 1hp AC motor depends on the specific motor design and manufacturer guidelines. It is important to consult the motor's documentation or contact the manufacturer to determine the correct capacitor value for proper motor operation.
What causes the fuse in your 1999 Pontiac grand prix controls the air conditioning to get hot and blow out?
Defective/Shorted Compressor Defective/shorted blower motor Defective/shorted cooling fan Disconnect each of the above one at a time to determine which area is the problem
How do you determine the frequency of a capacitor?
A capacitor alone doesn't have a frequency. The combinationof a capacitor and an inductor (coil) has.-- Read the value of capacitance printed on the capacitor, or measure it. Call it ' C '.-- Read the value of inductance printed on the coil, or measure it. Call it ' L '.The resonant frequency of the combination of those two components isF = 1 / (2 pi) sqrt(L C)
