A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. High … Meer weergeven Two typical schematic diagram symbols are as follows: • ANSI-style: (a) resistor, (b) rheostat (variable resistor), and (c) potentiometer • IEC resistor symbol Meer weergeven Ohm's law The behaviour of an ideal resistor is described by Ohm's law: Ohm's law states that the voltage ($${\displaystyle V}$$) across a resistor is proportional to the current ($${\displaystyle I}$$) … Meer weergeven Lead arrangements Through-hole components typically have "leads" (pronounced /liːdz/) leaving the body … Meer weergeven The value of a resistor can be measured with an ohmmeter, which may be one function of a multimeter. Usually, probes on the ends of test leads connect to the resistor. A … Meer weergeven Practical resistors have a series inductance and a small parallel capacitance; these specifications can be important in high-frequency applications. In a low-noise amplifier or pre-amp, the noise characteristics of a resistor may be an issue. Meer weergeven Adjustable resistors A resistor may have one or more fixed tapping points so that the resistance can be changed … Meer weergeven Production resistors Resistor characteristics are quantified and reported using various national standards. In the US, … Meer weergeven Web20 jul. 2024 · The purpose of a resistor is to be a thing that obeys Ohm's Law. That is to say, it's a thing that enforces a linear relationship between the current flowing through it and the voltage between its two ends. Sometimes we use a resistor when we want the current in some circuit to vary in proportion to the voltage that is forced upon the resistor. green tyre company uk
