Want to know the characteristics of capacitors? Then check it out! Here's the trick -- just look at the trick!
1: Basic concept of capacitance
Capacitor is a very common resistance device. It converts current into voltage and transmits it to a control circuit through a wire. A capacitor works simply by installing a small resistor on a power switch. When the circuit is turned on or off, the current flowing through this resistor creates a certain voltage drop. This ensures that the circuit does not pass the current point. This is 520L103KT16T. However, it is not easy to measure capacitance correctly. Because although the current size does not vary much, different types of capacitors need to match different parameters. For example :1. ΔFOCOSEL (resistance) represents the increase in impedance of a DC circuit when an AC signal passes through it; 2. IDMARKING (short for "power") indicates that the unit of energy on the output is wattages; 3. UPCAT (Rosenbach Partiton for short) represents the shape of a capacitor in Kelvin.
2: Measurement method and principle
Capacitance measurement methods are mainly as follows: 1, resistance method: the object to be measured through the conductor (wire) and the circuit board between the voltage, and then the voltage into the current. It is often used to measure large currents, such as the volume and capacity of fuel in the fuel tank in the aircraft. 2, voltmeter method: This measurement method is the use of measuring device measured voltage to represent the actual value of electricity, often used for battery charging battery between the voltage difference measurement, but the disadvantage is affected by temperature; 3. Galvanometer method: This measurement method requires the use of a special power supply to provide sufficient current. 4. Hall Effect tester: This is a new type of capacitance tester, which can be used to accurately detect various physical quantities inside the energy storage devices, including leakage current, dielectric loss, etc.
3: How to use the electronic meter to measure capacitance?
There are many ways to measure capacitance using an electronic meter, but the main way is through a resistor or other precision instrument. If you don't know how to choose the right measurement tool, here are some tips to consider: 1. Resistors: Many common resistors have some degree of accuracy and are not very expensive. 2. Other precision equipment requiring precision: laser sensors, microscopes, etc. 3. Test boards: Use a variety of different boards and scales in the lab so that capacitance can be measured more accurately. 4. Use professional equipment for measurement, such as Agilent's SHC1682A counter, which not only offers extremely high accuracy, but also provides maximum dynamic range.
