Resistor series

The Electronic Industries Association (EIA), and other authorities, specify standard values for resistors, sometimes referred to as the preferred . Individual resistors can be connected together in either a series connection, a parallel connection or combinations of both series and parallel, to produce more . The EIA preferred values can be summarised in tabular form to give the different values within each decade. These values are the common resistor values that . Resistor preferred or standard values: E series – E E E1 E2 E48. These standard resistor values are those which can be bought. If you look in a components catalogue you will discover that the resistor values appear to have been chosen by a musician! The ‘notes’ on the resistor scale are:- . Resistors are manufactured in series of standard resistance values according to the IEC standard.

The standard resistor value series depend on the tolerance. The current is the same through each resistor. The total resistance of the circuit is found by simply adding up the resistance values of the . Resistors can be connected in series; that is, the current flows through them one after another. The circuit in Figure shows three resistors connected in series, . EIA define standard series of resistor values: E E E1 E2 Eand E96. In industrial design, preferred numbers are standard guidelines for choosing exact product.

Use of the E series is mostly restricted to electronic parts like resistors, capacitors, inductors and Zener diodes. Renard series are a system of preferred numbers dividing an interval from to into 1 2 or steps. The French army engineer Colonel Charles Renard . Gå til Series and Parallel Resistors – Resistors are paired together all the time in electronics, usually in either a series or parallel circuit. Besides resistors in series, we can also have other elements in series – capacitors, inductors, diodes. These elements can be in series with other elements.

Table of Standard (E24) Resistor Values. If we wanted to build a simple series circuit with one battery and three resistors, the same “point-to-point” construction technique using jumper wires could be . Resistors are available in a number of standard ranges, often called ‘preferred values’ These ranges, or series, are set out by the . It turns out that we can always find the equivalent resistance by repeated application of two simple rules. These rules relate to resistors connected in series and .
