How to read resistors

Therefore, the first three bands indicate the significant digits, the fourth band is the multiplication factor, and the fifth band represents the tolerance. For the example shown here: brown (1), yellow (4), violet (7), black (x 100 = x1), green (0.5%) represents a 147 Ω resistor with a 0.5% tolerance.

How do you read a 4 digit resistor?

Resistor Code Format Similar to the three digit EIA, the four digit format uses the beginning values to indicate the significant digits while the last digit is the multiplier. 'R' is used to indicate the position of a decimal point. The four digit format allows for higher precision.

How do you read a resistor with a multimeter?

And take a resistor and touch the multimeter probes to the resistor. You can touch any prob any side

How do you read a 3 band resistor?

For a 3-band resistor color codes, the first two bands always denote the first two digits of the resistance value while the third band represents the multiplier. In the example we have, the bands are brown, black and brown. The first band is the brown band closest to the edge.

What do the numbers on resistors mean?

The Three and Four Digit Systems In these systems, the first two or three digits indicate the numerical resistance value of the resistor and the last digit gives a multiplier. The number of the last digit indicates the power of ten by which to multiply the given resistor value.

What do the markings on resistors mean?

The first two numbers represent the first two most-significant digits of the value, the last number represents a magnitude. In the above example picture, resistors are marked 104, 105, 205, 751, and 754. The resistor marked with 104 should be 100kΩ (10x104), 105 would be 1MΩ (10x105), and 205 is 2MΩ (20x105).

How do you read a resistor for dummies?

The first two bands represent the digits or significant figures the third band indicates the

What is 1k ohm resistor?

So, a 1k Ω resistor has a value of 1,000 ohms and the number we will code is 1,000.

What color is a 4 ohm resistor?

Color	Value
Red	2
Orange	3
Yellow	4
Green	5

How can you tell if a resistor is bad?

Set your meter to an appropriate range and connect the leads polarity does not matter compare your

How do I know what Ohm my resistor is?

Read the color bands from left to right. The colors on the first 2 or 3 bands correspond to numbers from 0 to 9, which represent the significant digits of the resistor's ohmic value. The last band gives the multiplier. For example, a resistor with brown, green and green bands is rated at 15 mega-ohms (15,000,000 ohms).

What does a reading of 0 ohms mean?

Resistance, symbolized by the (Ω) symbol and measured in Ohms, is a measurement of how well a current can travel through a circuit or a given path. A circuit with no resistance (0) would indicate a complete circuit, or one that has no short.

What color is a 47K resistor?

Resistance		47K ohm
Color Code		Yellow / Violet / Orange / Gold
Type		Carbon Film
Voltage	Maximum Operating	350V
Polarization		None

What color is a 470 Ohm resistor?

470 Ohm 2W High Quality Carbon Film Resistor (CFR) with ±5% Tolerance and Tin Plated Copper Leads. 470 Ohm Resistor Color Code: Yellow, Violet, Brown, Golden.

What does a 220 ohm resistor look like?

So, the color code of the 220 - ohm resistor is RED - RED - BROWN.

What color is a 1.5 K ohm resistor?

Value	First Color	Third Color
13	Brown	1.3 k
15 *	Brown	1.5 k
16	Brown	1.6 k
18*	Brown	1.8 k

How do I identify a 4.7 K resistor?

4.7k Ohm Resistor Color Code The four band 4.7k resistor is easy to recognize with its' distinctive pattern of yellow, violet, and red color bands. The 5 and 6 band versions have a pattern of yellow, violet, black, brown, followed by the tolerance band and temperature coefficient band on the 6 band version.

How do you read a 5 color resistor?

If the colors on a 5 band resistor is in this order: brown, green, red, blue and violet (as shown in figure). The values of color bands will be like this: Brown = 1, Green = 5, Red = 2, blue = 106, Violet = 0.10%.
