A single resistor may be used, or a pair (half bridge), or four resistors connected in a Wheatstone bridge configuration. The strain resistor is bonded with adhesive to an object that is subjected to mechanical strain. With the strain gauge and a filter, amplifier, and analog/digital converter, the strain on an object can be measured.
While discrete resistors in the range of few tens of megohm are very common, making giga-ohm range resistors is more complicated. Discrete resistors are available up to several tera-ohms, but are expensive because of limited demand.
For example, a 10 ohm resistor connected in parallel with a 5 ohm resistor and a 15 ohm resistor produces 1 / 1/10 + 1/5 + 1/15 ohms of resistance, or 30 / 11 = 2.727 ohms. A resistor network that is a combination of parallel and series connections can be broken up into smaller parts that are either one or the other.
Two decades of E12 values, which would give resistor values of 1 Ω to 82 Ω The E series is a system of preferred numbers (also called preferred values) derived for use in electronic components . It consists of the E3 , E6 , E12 , E24 , E48 , E96 and E192 series, [ 1 ] where the number after the 'E' designates the quantity of logarithmic value ...
Potentiometer – three-terminal variable resistor (variable voltage divider) [8] Trim pot – small potentiometer, usually for internal adjustments; Thermistor – thermally sensitive resistor whose prime function is to exhibit a large, predictable and precise change in electrical resistance when subjected to a corresponding change in body ...
A 75 Ω resistor, as identified by its electronic color code (violet–green–black–gold–red). An ohmmeter could be used to verify this value. Substances in which electricity can flow are called conductors. A piece of conducting material of a particular resistance meant for use in a circuit is called a resistor.
It is possible to synthesize a Loss-Free Resistor (LFR) by the combination of a switched mode converter and a suitable control circuit. The LFR is a two-port element that has a resistive i-v curve at the input terminals. The power absorbed at the input is transferred to the source that powers the total system, so in principle no losses occur.
A zero-ohm link or zero-ohm resistor is a wire link packaged in the same physical package format as a resistor. It is used to connect traces on a printed circuit board (PCB). This format allows it to be placed on the circuit board using the same automated equipment used to place other resistors, instead of requiring a separate machine to ...
