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 ...
Graph of two decades of E12 series resistor values, which gives resistor values from 1 to 82 ohms (Ω) The E series is another system of preferred numbers. It consists of the E1 , E3 , E6 , E12 , E24 , E48 , E96 and E192 series .
The strain gauge, invented by Edward E. Simmons and Arthur C. Ruge in 1938, is a type of resistor that changes value with applied strain. 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 ...
A 2.26 kΩ, 1%-precision resistor with 5 color bands (), from top, 2-2-6-1-1; the last two brown bands indicate the multiplier (×10) and the tolerance (1%).. An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others.
The two digits (from "01" to "96") are a code that indicates one of the 96 "positions" in the standard E96 series of 1% resistor values. The uppercase letter is a code that indicates a power of ten multiplier. For example, the marking "01C" represents 10 kOhm; "10C" represents 12.4 kOhm; "96C" represents 97.6 kOhm.
A similar non-standard notation using the unit symbol instead of a decimal separator is sometimes used to indicate voltages (i.e. 0V8 for 0.8 V, 1V8 for 1.8 V, 3V3 for 3.3 V or 5V0 for 5.0 V [24] [25] [26]) in contexts where a decimal separator would be inappropriate (e.g. in signal or pin names, in file names, or in labels or subscripts).
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.
The IEEE 315 standard contains a list of Class Designation Letters to use for electrical and electronic assemblies. For example, the letter R is a reference prefix for the resistors of an assembly, C for capacitors, K for relays.
