- Q:Capacitance for AC and DC effects?
- This current is also a sine wave, but with the resistance is different, although there is voltage current, but does not consume energy, called reactive power.
- Q:Use capacitance to do transformer how to calculate
- The principle of capacitor buck is not complicated. His working principle is to use the capacitor at a certain AC signal frequency to produce capacitive reactance to limit the maximum operating current. For example, in the 50Hz frequency conditions, a 1uF capacitance generated by the capacitive reactance of about 3180 ohms. When 220V AC voltage is applied to both ends of the capacitor, the maximum current flowing through the capacitor is about 70mA.
- Q:How to identify high voltage capacitors is good or bad
- There is a series in 220v AC power inside, see if the light bulb can be normal light. Determine if the capacitor has capacity. Whether the initial test is normal.
- Q:What is the electrolytic capacitor inside?
- There are aluminum foil, paper (not the general paper), as well as electrolyte. There is polarity, then the explosion will explode.
- Q:What is the phase-shifting capacitor, what is the difference between it and the general capacitor
- After the power is turned off, the charge will not disappear, nor will it be neutralized (after all, between the two plates is insulated, positive and negative charge can only attract each other, and can not be combined), so that the potential difference has been there until you To discharge, the bipolar plate with a wire, the electrons along the wire from the lower plate to move to the upper plate, the potential difference disappeared.
- Q:What is the principle of capacitance isolation?
- When the capacitor is connected to the AC circuit, there is also a charging process in which the charge is stopped when the capacitor voltage is equal to the supply voltage, and then the power supply voltage drops and the capacitor begins to discharge.
- Q:What is the difference between the power capacitor and the complement?
- Input compensation: three-phase co-fill capacitor input, the three groups of capacitors at the same time. The sub-capacitor can be put into operation separately.
- Q:Capacitance can pass high frequency resistance low frequency principle
- The capacitor has a charge and discharge time problem. When the positive half of the AC, to the capacitor charging moment, the circuit is a current flow, the equivalent of the channel, once the capacitor is charged, the circuit will not flow through, the equivalent of open circuit.
- Q:How to judge the capacitor is good or bad?
- Measurement, the choice of multimeter R × 10k block, with two test leads were any then the capacitor of the two pins, the resistance should be infinite. If the measured resistance (pointer to the right swing) is zero, then the capacitor leakage damage or internal breakdown.
- Q:Is the capacitor attached to the carbon foil positive?
- The above-mentioned positive and negative electrodes are wound around their central axis, and the core of the aluminum electrolytic capacitor is formed. Then, the core is placed in an aluminum shell and the aluminum electrolytic capacitor is formed.
