- Q:Capacitance for AC and DC effects?
- Current waveform ahead of the voltage 90 degrees, in a sine wave cycle, half of the time ( Voltage waveform 0-90 degrees and 180-270 degrees) power to charge the capacitor, while the other half of the time (voltage waveform 90-180 degrees and 270-0 degrees) capacitance of the power discharge, the power and intact return power The
- Q:What is the difference between the reactor and the capacitor?
- Reactor is the inductance ah, usually magnetic components plus winding wound, storage of magnetic field energy, the capacitor is stored in the electric field energy.
- 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.
- Q:What is the use of capacitors?
- As a passive component of the capacitor, its role is nothing more than the following; applied to the power circuit, to achieve bypass, decoupling, filtering and energy storage role, the following classification:
- 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:What is the electrolytic capacitor inside?
- Electrolytic capacitor is a dielectric of a dielectric electrolyte coating has a polarity, positive and negative can not be connected wrong. Electric capacity (Electric capacity), by the two metal pole, the middle folder with insulating material (medium) composition.
- Q:What is the phase-shifting capacitor, what is the difference between it and the general capacitor
- And the phase-shifting capacitor has the function of changing the phase of the alternating current signal in addition to the characteristics of the general capacitor. The answer can be compensated by the power factor compensation in parallel with the phase-shifting capacitor, and the phase-shifting capacitor can be used to produce the phase-shifting capacitor fault diagnosis device.
- 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:On the ground resistance, what role the capacitor
- Coupling: The capacitance used in the coupling circuit is called the coupling capacitor, which is used in the capacitive coupling amplifier and other capacitive coupling circuits to make use of this capacitor circuit.
- 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.
