- Q: Is the capacitor attached to the carbon foil positive?
- In order to facilitate the manufacture of capacitors, usually the electrolyte solution is immersed in special paper, and then with a place of aluminum and immersion in electrolyte solution with the paper together, so you can more easily in the original aluminum foil to lead the negative.
- Q: What are the differences between capacitors and capacitors?
- There is a capacitor is a unit of the capacitor is a substantial object ah
- Q: What is the relationship between capacitance and voltage?
- The larger the capacity of the capacitor, the larger the voltage, the smaller the capacity (uF). Since q = Cu, q is the current charge number of the capacitor, which is substantially proportional to the volume of the capacitor
- Q: Does the size of the capacitor affect the power consumption?
- Capacitors are essential electronic components, it acts as a smoothing filter in the electronic equipment, power supply and decoupling, AC signal bypass, AC-DC circuit AC coupling, etc. Because the type of capacitor and the type of structure more
- Q: What is the principle of capacitance isolation?
- When the supply voltage rises in the reverse direction, the capacitor is charged in the reverse direction, and then the discharge is reversed. So the charge and discharge and the AC current is really the same, so the capacitor can pass the AC current.
- Q: What is the difference between the power capacitor and the complement?
- Wiring, three-phase complementary capacitor has three terminals, respectively (A, B, C) sub-capacitor has four terminals, respectively, then
- Q: How to judge the capacitor is good or bad?
- Due to the amplification of the composite transistor, the measured capacitance of the charge and discharge process to be amplified, so that the multimeter pointer increase the amplitude, so easy to observe. It should be noted that: in the test operation, especially in the measurement of small capacity capacitance, it is necessary to repeatedly change the measured capacitance of the pin contact A, B two points, in order to clearly see the multimeter pointer swing.
- Q: On the ground resistance, what role the capacitor
- Decoupling: The capacitor used in the decoupling circuit is called the decoupling capacitor. This capacitor circuit is used in the DC voltage supply circuit of the multi-stage amplifier. The decoupling capacitor eliminates the harmful low frequency cross-connection between the amplifiers.
- Q: How to identify high voltage capacitors is good or bad
- Test the resistance at both ends with a multimeter. If the use of a pointer multimeter, and most of the same capacitor, you can see the pointer from small to large a swing process. The difference is not the last return to infinity, but 10m. Inexperienced friends may think that the capacitor breakdown or leakage, in fact, not.
- Q: Why does the circuit current gradually decrease when charging the capacitor?
- due to the increase in the number of charge, the electrostatic field field strength will gradually increase, increasing the field strength caused by the absorption of electrons to produce exclusion, So that the number of adsorbed charges gradually reduced, the number of charge to reduce the performance of the phenomenon that the charging current is gradually reduced. When the number of charges on the two electrode plates of the capacitor reaches a gradually increasing field strength constraint, the amount of charge is not increased and the equilibrium state is reached, that is, the charge saturation current is zero.
