4 Band Resistor Color Code

4 band resistor color code

The 4-band resistor color code is the most commonly used resistor. Similar to the 3 band resistor, the first two bands always give the first 2 digits of the resistance value. The third band represents the multiplier while the fourth band represents tolerance.

Which color represents digit 4 in resistor color code?

To distinguish left from right there is a gap between the C and D bands. For example, a resistor with bands of yellow, violet, red, and gold will have first digit 4 (yellow in table below), second digit 7 (violet), followed by 2 (red) zeros: 4,700 ohms.

How do I find the Colour code of a resistor?

Calculating Resistor Colour Code Values For example, a resistor has the following coloured markings; Yellow Violet Red = 4 7 2 = 4 7 x 102 = 4700Ω or 4k7 Ohm. The fourth and fifth bands are used to determine the percentage tolerance of the resistor.

What does the first color in the 4 band resistor stands for?

The 1st color band on the resistor indicates the 1st significant value or 1st digit of the resistors resistance and the 2nd color band indicates 2nd significant value or 2nd digit of the resistors resistance. The 3rd color band is the decimal multiplier and the 4th color band indicates the resistors tolerance.

How do I identify a resistor band?

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

What is the difference between a 4 band resistor and a 5 band resistor?

As we see in the above image a 5 band resistor has an extra digit before you get to the multiplier band, this allows for more precision in describing the value of the resistor which is important as most 5 band resistors are higher precision, having a tolerance of 1% to 2% while 4 band resistors typically have

What do you call the 4th band in a 5 band resistor?

5 Band Resistor with a 4th Band of Gold or Silver The first two bands represent the significant digits, the third band is a multiplication factor, the fourth band is for tolerance and the fifth band is for the temperature coefficient (ppm/K).

What color is a 470 ohm resistor?

470 Ohm 0.5W High Quality Carbon Film Resistor (CFR) with ±5% Tolerance and Tin Plated Copper Leads. 470 Ohm Resistor Color Code: Yellow, Violet, Brown, Golden.

What are the 5 types of resistors?

What color is 22K resistor?

22K Ohm Resistor Color Code: Red, Red, Orange, Golden. Resistance: 22K Ohm, Power Rating: 1 Watt, Approximate Maximum Current: 6.74mA ..

How do you read a color band resistor?

Always read resistors from left to right. - Resistors never start with a metallic band on the left. If you have a resistor with a gold or silver band on one end, you have a 5% or 10% tolerance resistor. Position the resistor with this band on the right side and again read your resistor from left to right.

What represents the second color of a 4 band resistor?

The color of the second band indicates the value of the second significant digit. The third color band represents a decimal multiplier by which the first two digits must be multiplied to obtain the resistance value of the resistor.

How do you read a color code?

Hex color codes start with a pound sign or hashtag (#) and are followed by six letters and/or numbers. The first two letters/numbers refer to red, the next two refer to green, and the last two refer to blue. ... For example:

A=10.
B=11.
C=12.
D=13.
E=14.
F=15.

What do resistor colors mean?

A gold band represents a tolerance of +/-5%, and a silver band represents a tolerance of +/-10%. If no tolerance band is present, the tolerance is +/-20%. There are some resistors with smaller tolerances, but gold and silver are the most common tolerance band colors.

How do you calculate resistors?

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

What is 4.7K resistance?
