A resistor is marked with the following color bands brown black red and gold What is the resistance of this resistor?
The color bands on a resistor represent the resistor's resistance value. In this case, the colors brown, black, red, and gold correspond to the digits 1, 0, 2, and a multiplier of 10%, respectively. Therefore, the resistance of this resistor can be calculated as 10 * 10^2 ohms, which equals 1000 ohms or 1 kiloohm.

Describe the purpose of the coloured bands on a resistor?
The colored bands on a resistor indicate its resistance value and tolerance. By interpreting the color code, you can determine the resistance value of the resistor and the range within which the actual resistance may vary. This helps in identifying, sorting, and using resistors in electronic circuits.
What do the colours on resistor mean?
The colored bands on a resistor represent the resistor value and tolerance. The first two bands indicate the significant digits of the resistance value, the third band represents the multiplier, and the fourth band (if present) indicates the tolerance of the resistor. By decoding these colors, you can determine the resistance value of the resistor.
What is the value of a resistor marked with Brown Yellow White Black bands?
149 ohms, I believe.
How is resistance calculated?
You can measure it, but you can't calculate it. That's why the resistance of a resistor is always printed on it, either in numbers or in color bands. Without that marking, the resistor is pretty useless. If it accidentally missed being marked during manufacture, it would be either discarded, or sold surplus for bubkes.
What is the resistance value and tolerance with color bands of gray red black and gold?
The resistance value for the resistor with color bands gray-red-black-gold is 82 ohms with a tolerance of +/- 5%.
Why are there couler bands on a resistor?
Color bands are used on resistors to indicate their resistance value and tolerance. Each color represents a digit, and by combining multiple colors, you can determine the resistance value. The bands help quickly identify the resistor's value without needing to use a multimeter or other measuring tools.
What do the different colours on a resistor mean?
The color bands on a resistor indicate its resistance value. Each color corresponds to a digit, which is used to calculate the resistance value based on a specific color code chart. The tolerance of the resistor is also indicated by a separate color band.
What is the maximum allowable resistance of a 680ohms resistor?
This depends on the tolerance rating of the resistor. There's 1, 2, 5, 10% tolerances. For tighter tolerances, you pay a premium - you can get tolerances as close as .1%. This is defined by one of the bands on the resistor. For a 10% tolerance, the maximum resistance of a 680 ohm resistor could be 748 ohms.
What do the lines on the resistor mean?
They are color coded lines (or Bands) that are usually broken down into 2 parts. the first part of the bands are to establish the amount of resistance the resistor is constructed, by design, to perform in a circuit. The second part (which is the usally the last line or band) extablishes the amout of tolarance the designed resistor has. tolorance bands are always silver or gold if they are there but there is a provision where you may not see a tolorance band. There are plenty of electronis sites that can break down the color codes for you. but they are based on a X10, X100, X1000... mutipliers depending on which position the band is located in ie. first, second, third and so on... and for how many there are.
What will be the resistance of carbon resistor having the green and golden colour bands?
Green is 5ohms and gold is 5% tolerance. It depends if there are other bands though. See related link
How do you work out resistance?
Resistance is calculated using Ohm's Law, which states that resistance (R) is equal to the voltage (V) across a circuit divided by the current (I) flowing through it, R = V/I. Resistance can also be determined using the color bands on a resistor in a circuit by referring to a resistor color code chart.
What 4 colour bands represent a resistor with resistance of 270 k ohms and a tolerance of 5 percent?
