Why does resistance value measured using multimeter differ from one decoded using colour band?
Resistors have tolerance. So does the multimeter. Standard resistors range from 20% (no fourth band), to 10% (fourth band silver), to 5% (fourth band gold). Resistors will not normally measure exactly what you expect, and proper circuit design must take this into account.The multimeter may not be calibrated correctly.

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 does colour temperature measure?
Color temperature measures the color appearance of a light source, indicating whether the light appears warmer (yellowish) or cooler (bluish). It is measured in Kelvin (K), with lower values representing warmer light and higher values indicating cooler light.
Light absorption by a pigment is measured for red blue green and yellow light what is the dependent and the independent variable?
The dependent variable is the amount of light absorbed by the pigment, as this is the outcome that is measured. The independent variable is the color of the light used (red, blue, green, yellow), as this is the factor that is being manipulated to observe its effect on light absorption.
What gives the color to the light in the bulb?
The color of the light produced by a bulb is determined by the type of filament or gas inside. For example, tungsten filaments produce a warm yellow light, while fluorescent bulbs use phosphors to convert UV light into visible light. LED bulbs use a semiconductor to emit light, and the color can be adjusted by using different materials.
What does phiscal properties mean in science?
Physical properties in science refer to characteristics of a substance that can be observed and measured without changing the composition of the substance. Examples include color, density, melting point, boiling point, and conductivity. These properties help us identify and classify different materials.
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.
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.
How long is a color in cm?
A colour cannot be measured in centimetres.
What does the colour signifies in a 'Diode'?
The color bands identify resistance
Why do resistors have a color code?
Colour code used to identify resistance of the resistor
How do you find out the un known resistance value?
1.Use of ohmeter. Connect the ohmeter terminals to the the ends of the unkown resistance and take the reading. Adjust the range to give a good accuracy. 2. Use of colour codes. This applies if the unknown resistance is of a resistor with visible colour codes on it.
What is the measurement of diamonds?
Diamonds are measured by:clarity -- flawless or flawed with many degrees of flawed;carat -- the weight of the stone;cut -- the excellence of faceting and the shape of the 'cut';colour -- the lack of colour or degree of colour visible in the stone.
What does qualitative data consist of?
Qualitative data is information that can not be measured, such as the colour of your eyes. Qualitative data descriobes
What to measure in a diamond?
Diamonds are measured by carat weight, clarity, colour and excellence of the cut, some of which are named.
How do you test to identify a bad resistor?
First you need to know the value of the resistor. Follow the link for a handy resistor calculator After determining the value of your resistor simply test the resistor with an ohmmeter to see if it is at true value. General use should be within + or - 5%
What data cant be measured but divided into groups?
I suspect that the answer is meant to be qualitative data but that is not a proper answer. Information about the qualitative aspect of data (eg what colour is you hair) is still a measurement. It may not be numerical measurement, but the question states "can't be measured", not "can't be measured numerically".
What is the color scheme of resistors?
