How do you decode a 5 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 is the 5th band on a resistor?
tolerance
5 band resistor Resistors with high precision have an extra band to indicate a third significant digit. Therefore, the first three bands indicate the significant digits, the fourth band is the multiplication factor, and the fifth band represents the tolerance.
How do you calculate resistor code?
Reading and Determining the Resistor Value Hold the resistor with the gold or silver band to the right and read the color codes from the left to the right. Select the color codes from the bands on the resistor. Read the colors from left to right. The resistance value based on the color code provided is now displayed.
What is the color code for a 5k tolerance 5 resistor?
The colors brown, red, green, blue, and violet are used as tolerance codes on 5-band resistors only. All 5-band resistors use a colored tolerance band. The blank (20%) “band” is only used with the “4-band” code (3 colored bands + a blank “band”).
How do you count resistor color codes?
Calculating Resistor 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 color denotes the tolerance value of 5?
Gold signifies that the tolerance is ±5%, so the real resistance could lie anywhere between 4,465 and 4,935 ohms.
How do I teach students the resistor color code?
The normal way to teach students the resistor color code is to show them the code first, then show them some resistors. Here, the sequence is reversed: show the students some resistors, and have them figure out the code.
How to identify a resistor?
A resistor is identified by its pattern of color of bands. There are 4, 5 and 6 band resistors. To calculate the resistance of a resistor, you can select the appropriate color bands in the above resistor color code calculator. How to calculate the resistance?
How do you calculate the resistance of a 5 band resistor?
Let’s take an example of a 5-band resistor with the colors given in the above image (brown, green, red, black and gold). So according to the formula the resistance will be: 152 * 1 = 152 Ohms with 5% tolerance.
What does the 4th band of a resistor represent?
4-Band: Reading the resistor from left to right, the first two color bands represent significant digits, the third band represents the decimal multiplier, and the fourth band represents the tolerance.
