What are typical resistor values?
What are typical resistor values?
The most common series are:
- E6 20% tolerance.
- E12 10%
- E24 5% (also available with 1%)
- E48 2%
- E96 1%
- E192 0.5% (also used for resistors with 0.25% and 0.1%).
What is a normal resistance for a resistor?
Most resistors you’ll see range between 1 ohm and 1 megaohm (1.0 MΩ) they often have 5% tolerance but you can buy 1% or even 0.1% accuracy resistors. In general, resistence testing is best for measuring resistors, but you may find yourself measuring the resistance of other things, such as sensors and speakers.
What are standard resistors?
Standard resistors are very high precision resistors used as a reference to calibrate or verify the accuracy of other resistors in industry or establishments, on lines or production equipment. these are also used to check the accuracy of resistance meters by most manufacturers.
What are E24 values?
E series of standard resistor values
| Summary of EIA Preferred or Standard Resistor value Series | ||
|---|---|---|
| E Series | Tolerance (Sig Figs) | Number of values in each decade |
| E24 | 5% [normally also available in 2% tolerance] | 24 |
| E48 | 2% | 48 |
| E96 | 1% | 96 |
What is the value of resistor 1?
Standard Resistor Values
| 1% Standard Values (EIA E96) Decade multiples are available from 10.0 Ω through 1.00 MΩ (also 1.10 MΩ, 1.20 MΩ, 1.30 MΩ, 1.50 MΩ, 1.60 MΩ, 1.80 MΩ, 2.00 MΩ and 2.20 MΩ) | ||
|---|---|---|

| 31.6 | 32.4 | 36.5 |
| 42.2 | 43.2 | 48.7 |
| 56.2 | 57.6 | 64.9 |
What is E24 series resistors?
The different sets of standard resistor values are known by their E-series numbers: E6 has six resistance values in each decimal interval, E12 has twelve, E24 has twenty-four and so forth.
What is e resistance?
E most likely stands for an E series resistor e.g. E24 – preferred value resistor see resistorguide.com/resistor-values. – JIm Dearden.
How do you find the standard value of a resistor?
The basic unit of resistance is the ohm (Ω). Standard base resistor values are given in the following tables for the most commonly used tolerances (1%, 2%, 5%, 10%), along with typically available resistance ranges. To determine values other than the base, multiply the base value by 1, 10, 100, 1k, or 10k.
What does the wattage mean on a resistor?
Wattage means how much power the physical resistor is rated to handle. The rating is always for given conditions, such as the ambient temperature, or when mounted on a heat sink. You determine the power in a resistor by computing the voltage across times the current thru it.
What is the standard value of a resistor?
Standard Resistor Values. This page provides a quick reference for standard resistor values based on a specified tolerance. Standard Resistor Values : 0.1%, 0.25%, 0.5%. Standard Resistor Values : 1%. Standard Resistor Values : 5%. Standard Resistor Values : 10%.
What is the importance of the wattage of a resistor?
This is why resistors are given power ratings- to specify the maximum allowable amount of power that can pass through it . If this wattage of power is exceeded, the resistor may not be able to withstand the power and may melt and can create a short in a circuit, which can lead to even greater hazards for the circuit.
When 1 mega ohm resistors are used?
A nominal 1 megohm resistor is commonly used in wrist straps and to ground work surfaces. In the event of an operator touching an energized conductor, for the normal mains electricity supplies this resistor will limit the current flowing through the person to less than 0,5 mA.
