Resister function
WebWhen the switch is closed, the input voltage at the gate goes to ground. In electronic logic circuits, a pull-up resistor ( PU) or pull-down resistor ( PD) is a resistor used to ensure a known state for a signal. [1] It is typically used in combination with components such as switches and transistors, which physically interrupt the connection ... 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-power … See more Two typical schematic diagram symbols are as follows: • ANSI-style: (a) resistor, (b) rheostat (variable resistor), and (c) potentiometer • IEC resistor symbol See more 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 ($${\displaystyle I}$$) … See more Lead arrangements Through-hole components typically have "leads" (pronounced /liːdz/) leaving the body "axially", that is, on a line parallel with the part's longest axis. Others have leads coming off their body "radially" instead. Other components … See more 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 simple ohmmeter may apply a voltage from a battery across the unknown resistor (with an … See more 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. See more Adjustable resistors A resistor may have one or more fixed tapping points so that the resistance can be changed by moving the connecting wires to different terminals. Some wirewound power resistors have a tapping point that can slide … See more Production resistors Resistor characteristics are quantified and reported using various national standards. In the US, MIL-STD-202 contains the relevant test methods to which other standards refer. There are various … See more
