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 … 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 … 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 … See more Adjustable resistors A resistor may have one or more fixed tapping points so that the resistance can be changed by … See more Production resistors Resistor characteristics are quantified and reported using various national standards.

WebThat word wasn't invented yet. "Point contact solid state amplifier"? But Shockley's invention became "transistor" for "transfer"+"resistor", but what sense, you ask, does that make? Current flowing between emitter and collector is a "transfer" of charge. It is not a good conductor - it is a resistor.
