What is the resistance and tolerance of a four band resistor with the following colors greenblueorangegold?
the 4 colour resistor colour code is thus:
black = 0
brown = 1
red = 2
orange = 3
yellow =4
green = 5
blue = 6
violet = 7
grey = 8
white = 9
the first two numbers are found directly on the table.
the third number is not the number, but the number of zeros at the end.
therefore the value is yellow = 4, green = 5, and brown equals 1 zero, so the total is 450 ohms.
the gold band indicates tolerance. gold is by far the most common, and indicates a tolerance of +/- 5%. therefore the actual value of the resistor could be anywhere between 427.5 and 472.5.
What else can I help you with?
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.
What is the concept of resistor tolerance and its importance?
Resistor tolerance is how accurate the resistor value is. You may have a 10% tolerance, 820 ohm resistor, which means the actual value of resistance is 820 ohms +/- 82 ohms. If you design a circuit that has very stringent requirements for resistor values, you may need to purchase a resistor that has a smaller tolerance (like 5, 2, 1, .5%). The smaller the tolerance, the more expensive it will be (generally).
What the function of tolerance for resistor colour code?
Tolerance indicates how much the measured value of a resistance is different from its theoretical value, and it is calculated using percentages.
What is the purpose of specifying the tolerance of a resistor?
on electronic components, of course, can not be made absolutely perfect. so there must be imperfections in the making, it is called tolerance. for ex: 100ohm resistor ,a tolerance of 5%, meaning the resistance between 95-105ohm (100ohm * + / -5%). not fit 100ohm.
When 10 ohm resistor and 100 mega ohm resistor are connected in series then what will be the combined resistance?
100 megohm the 10 ohms completely vanishes in the tolerance of the 100 megohm resistor, in that range tolerances can exceed 20% of nominal.
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 resistance value and tolerance of a resistor with Brown Green Red Silver?

What is the upper control limit of a 1 ohm resistor with a 20 percent tolerance?
A 1 ohm 20% tolerance resistor should not exceed 1.2 ohms actual resistance.
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 is The plus minus limits of a resistors marked value called?
The plus-minus limits of a resistor's marked value are referred to as its tolerance. Tolerance indicates the acceptable range of variation from the specified resistance value, usually expressed as a percentage. For example, a resistor with a marked value of 100 ohms and a tolerance of ±5% can have an actual resistance between 95 ohms and 105 ohms. Tolerance helps in determining how closely a resistor's actual resistance matches its rated value.
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 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%.
What the function of tolerance for resistor colour code?
Tolerance indicates how much the measured value of a resistance is different from its theoretical value, and it is calculated using percentages.
When a manual refers to a particular resistor as 2.2 megohm resistor does this means the resistor can safely carry a current of 2200000 amperes?
No. It means it has a resistance of 2,200,000 Ohms. Plus or minus the tolerance.
