Q:Capacitance can pass high frequency resistance low frequency principle
This process of current flow will soon end, the specific length of time and the resistance of the circuit and the size of the capacitor, the larger the size of the product the greater the charging time, the shorter the contrary. After charging is complete, the voltage across the capacitor is equal to the size of the DC supply voltage
Q:Low voltage capacitor voltage 0.45 and 0.4 What is the difference between usage
0.45 and 0.4 capacitors are capacitors that rated the line voltage of 0.45kV and 0.4kV; they are suitable for 380V voltage systems, the difference lies in their pressure rating;
Q:Why does the circuit current gradually decrease when charging the capacitor?
The capacitor is a charged container, when the container is full of charge when the internal potential and external potential can reach equilibrium, then the circuit of electrons no longer exercise.
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:What is the difference between polyester film capacitors and ceramic capacitors?
Polyester capacitor medium for the polyester film, its capacity and pressure range, small size, large capacity, high temperature, low cost. But tgδ with the frequency changes, it is used for tgδ, stability and loss requirements are not high occasions, such as DC and pulsating circuit.
Q:What are the differences between capacitors and capacitors?
Capacitance is a large category, and capacitors are subclasses of capacitors. Capacitors can be divided into cbb capacitors, aluminum electrolytic capacitors, safety capacitors and so on. Different categories, the difference is still relatively large
Q:Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?
With the increase in stray inductance, IGBT turn-on loss will be reduced, the diode loss will increase. Stray inductance may also cause oscillations, such as oscillations caused by current mutations, which may result in limited device use due to EMI or overvoltage limits.
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:What is the capacitor, what is the use, where is there?
Capacitor is the storage of the charge of the container, usually by two pieces of metal foil (or metal film) in the interval between the air, paper, mica, plastic film and other insulating materials. Commonly used to improve the power factor, start single-phase asynchronous motor,
Q:Cd capacitance to express what
Using polypropylene film as a medium, with a special electrode to the cylindrical core connected into a series structure, the core wrapped plastic tape, both ends with flame retardant epoxy resin package. With a small self-inductance, equivalent series resistance is low, loss is small, high insulation resistance, good frequency characteristics and can withstand high voltage, high current impact and other characteristics.
