Q:Does the size of the capacitor affect the power consumption?

Therefore, users not only need to understand the performance of various types of capacitors and general characteristics, but also must understand the advantages and disadvantages of various components under given use, mechanical or environmental constraints, etc. This article describes the main parameters of the capacitor and application , For readers to choose the type of capacitor used.

Q:What is the electrolytic capacitor inside?

Electrolytic capacitor inside the composition of the structure: two close to each other with a coating with polarity, positive and negative metal electrode plate, the middle folder with insulating material (medium for the electrolyte,) constitute

Q:How does the capacitor work? What does it do?

Straight to pass on the circuit need to pass the AC signal, power supply filter, cut off DC and other places to use. Capacitor charge and discharge is the basis of other properties. There are two kinds of filtering, one is the power filter, which is more obvious charge and discharge, can be seen as a container.

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:Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?

The stray inductance is represented by conductors in the circuit, such as connecting wires, component leads, element bodies, etc.

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?

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:How to use the capacitor

Solid-state aluminum capacitors have positive and negative points, do not reverse the solid-state aluminum capacitors, reverse solid capacitors can lead to a sharp increase in leakage current or reduced service life.

Q:Use capacitance to do transformer how to calculate

According to this feature, if we connect a resistive element in series with a 1uF capacitor, the voltage obtained at both ends of the resistive element and the power dissipation it generates depends entirely on the characteristics of the resistive element.

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;
