0.5USD Inductor Switch



Low-power resistors are usually made of carbon membranes encapsulated in plastic housings, while high-power resistors are usually wire wound resistors made by winding high-resistivity metal wires around a ceramic core.
If a resistor has a resistance value close to zero ohms (for example, a large-section wire between two points), the resistor has no hindrance to the current, and the parallel circuit of such a resistor is short-circuited and the current is infinite. If a resistor has an infinite or large resistance, the circuit in series with this resistor can be considered as an open circuit and the current is zero. Resistors commonly used in the industry are between two extremes. They have a certain resistance and can pass a certain current, but the current is not as large as when they are short-circuited. The current limiting effect of the resistor is similar to the effect of limiting the flow of water through a small diameter tube connected between two large diameter tubes. Resistance, the English name resistance, is usually abbreviated as R, which is a basic property of a conductor and is related to the size, material, and temperature of the conductor. Ohm's law states that I=U/R, then R=U/I, the basic unit of resistance is ohms, which is represented by the Greek letter “Ω”. There is a definition that generates one ampere current when one volt is applied to a conductor. The corresponding resistance. The main function of the resistor is to hinder the flow of current. In fact, "resistance" refers to a property, and the resistance usually referred to in electronic products refers to a component such as a resistor. Ohm is often referred to as Europe. The commonly used units that represent resistance are kiloohm (kΩ), megohm (MΩ), and milliohm (m Ω).
