Screwdriver definitionA common tool used to turn a screw to hold it in place, usually having a thin wedge head that can be inserted into the slot or notch of the screw head.Technical principleThe working principle of the wheel shaftScrewdriver classification Ordinary screwdriver Combined screwdriver Electric screwdriver Watch driver Small diamond screwdriver

Measuring pen definition123An electrical tool used to test electrical wiring for electrical power.Measuring pen working principleWhen measuring the live wire, there is a voltage U=220V between the live wire and the ground, and the resistance inside the measuring pen is usually about several megaohms. The current through the measuring pen (that is, the current through the human body) is very small, usually less than 1 mA. When such a small current passes through the human body, it will not hurt p

The role of common electrical toolsElectricians in the installation and maintenance of various power supply and distribution lines, electrical equipment and lines, are inseparable from a variety of electrical tools, such as screwdrivers, wire cutters, wire strippers and so on. There are many kinds of commonly used electrical tools and many uses, and the following is a brief introduction.Sort with electrical toolsTester pen: A common tool used to measure whether a tool is energized.Multimeter: Us

What is an IGBT?IGBT DefinitionAn Insulated Gate Bipolar Transistor (IGBT) is defined as a semiconductor device that combines the advantages of Power MOSFETs and Power BJTs.StructureThe IGBT structure includes an additional p+ injection layer, which enhances its performance compared to PMOSFETs.Switching Characteristics of IGBTIGBT switching involves distinct turn-on and turn-off times, with specific delay and rise/fall times affecting performance.Latching UpLatching up occurs when the IGBT stay

What is Reciprocity Theorem?Reciprocity Theorem DefinitionThe reciprocity theorem states that in a reciprocal circuit, the current remains the same when the positions of the voltage source and ammeter are swapped.Reciprocal CircuitA circuit that follows the reciprocity theorem, where voltage and current are interchangeable, is called a reciprocal circuit.Ideal ComponentsFor the reciprocity theorem to work, both the voltage source and ammeter must have zero internal resistance.Transfer Resistance
