product description 

3BHB030422R0002 is RESISTOR 147KWS, 2K82, 10% PULSE

The size of the resistance value of the resistance element is generally related to temperature, material, length, and cross-sectional area, and the physical quantity that measures the size of the resistance affected by temperature is the temperature coefficient, which is defined as the percentage of the change in the resistance value for every increase in temperature of 1℃. The main physical feature of the resistance is the conversion of electricity to heat energy, it can also be said that it is an energy-consuming element, and the current through it generates internal energy. Resistance in the circuit usually plays the role of voltage division and shunt. For signals, both AC and DC signals can pass through resistors.

effect

Low-power resistors are usually composed of carbon films encapsulated in a plastic housing,

 while high-power resistors are usually wire wound resistors,

 made by winding a high-resistivity metal wire around a porcelain heart.

If the resistance value of a resistor is close to zero ohms (for example, a large cross-section wire between two points), the resistor has no hindering effect on the current, and the circuit in parallel with such a resistor is short-circuited, and the current is infinite. 

If a resistor has an infinite or large resistance, the circuit connected to the resistor can be regarded as open and the current is zero. Resistors commonly used in industry are between the two extreme cases, it has a certain resistance, can pass a certain current, but the current is not as large as when the short circuit. The current limiting effect of a resistor is similar to that of a small diameter pipe connected between two large diameter pipes to limit the flow of water. resistance, the English name resistance, is usually abbreviated to R, which is a basic property of conductors,

 and is related to the size, material and temperature of conductors. Ohm's law says that I=U/R, then R=U/I, the basic unit of resistance is ohms, expressed by the Greek letter "Ω", there is such a definition: when a voltage is added to the conductor, the corresponding resistance value of an ampere current is generated. The main function of resistance is to prevent the flow of current. In fact, "resistance" refers to a property, and the resistance usually referred to in electronic products refers to such a component as a resistor. Ohm is often shortened to Ohm. The common units that indicate the resistance value are also thousand ohm (kΩ), megohm (MΩ), milliohm (mΩ).
