## What does 1% on a resistor mean?

Most five band resistors are precision resistors with tolerances of either 1% or 2% while most of the four band resistors have tolerances of 5%, 10% and 20%. The colour code used to denote the tolerance rating of a resistor is given as: Brown = 1%, Red = 2%, Gold = 5%, Silver = 10 %

## What are the standard resistance values of resistor?

Preferred Values or E-series The series looks as follows: 1– 1.2 – 1.5 – 1.8 – 2.2 – 2.7 – 3.3 – 3.9 – 4.7 – 5.6 – 6.8 – 8.2 – 10 etc. All of these values can be powers of ten (1.2 – 12 – 120, etc.). While the E12 series is the most common, other series are also available.

**How do you find the standard resistance value?**

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 is percentage resistor value?

Tolerance is the percentage of error in the resistor’s resistance, or how much more or less you can expect a resistor’s actual measured resistance to be from its stated resistance. A gold tolerance band is 5% tolerance, silver is 10%, and no band at all would mean a 20% tolerance.

### What is the color code for 1 ohm resistor?

1 Ohm Resistor Color Code: Brown, Black, Golden, Golden. Resistance: 1 Ohm, Power Rating: 0.25 Watt, Approximate Maximum Current: 500mA .

**What is standard resistor?**

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 is the Colour code of 1k resistor?

1K Resistor Color Chart

Band Number | Function | Color |
---|---|---|

1 | 1st Digit | Brown |

2 | 2nd Digit | Black |

3 | Multiplier | Red |

4 | Tolerance | Gold (or silver) |

#### What is the colour code of 1 Mega ohm?

1M Ohm Resistor Color Code: Brown, Black, Green, Golden. Resistance: 1M Ohm, Power Rating: 0.25 Watt, Approximate Maximum Current: 0.5mA .

**What is a 5% resistor?**

The tolerance gives the % deviation that the real value is allowed to be different from the stated or nominal value. For example, a 100-ohm 5% resistor can be anywhere between 95 and 105 ohms. If you find a 5% resistor that is exactly the nominal value, i.e. 100 ohms, then that is just plain luck.

## How do you determine the value of a resistor?

– measure it with a meter – infer it from voltage and current measurements – read the value marked on the body – read the schematic and or BOM/parts list – ask the Engineer who designed it

## How to determine resistor value?

B = 0.1%

**What is nominal resistor value?**

The nominal value of a resistor is the value indicated by the color bands or the value printed on the resistor. Its a design and manufacturing goal, for example 1000 Ohm resistors are mass produced, very few measure 1000 Ohms. The tolerance is a plus and minus % Ohms value.
