Resistors have standard colors for identification of the resistance value. In order, the colors are: black, brown, red, orange, yellow, green, blue, violet, gray, and white. Reading resistors is a very simple procedure if you use the chart and formula below.
Hold the resistor with the gold or silver band to the right and read the resistor from the left to the right.

Equation for Resistor serial and parallel?
In series, you just add the resistor values together to find the total resistance. In parallel you can use the following equation you can find the total resistance by multiplying the lowest and highest resistor value, the dividing that by the sum of all the resistor values you have in parallel. you could also take the inverse of all the inverses of you resistor values added together.
How do you find unknown value of a resistor when total resistor values and voltage are known in a series circuit?
A: If you know the total resistance and total voltage then you know total current flow for the circuit, this current will be same for every resistor in series however the voltage drop will change for each resistor . So measuring the voltage drop across the resistor in question and divide by the total current will give you the resistor value.
Why are fixed resisters used in many circuts?
Hi, where there is no need of changing the value of resistor then why do you place variable resistor instead a fixed resistor. After all the selection of resistor depends on the cause of use in application. by the way wide range of resistor values are avilable in the market. if the application requires tuning operation then variable resistor is need to be mounted. nothing is mandatory unless the application requires.

When a voltmeter is connected to a resistor what will it read?
If you place an OHM meter across a resistor, it will read resistance. An OHM meter set to read voltage will read any voltage present. So, if you pick up a resistor, connect it to a volt meter, in theory, no voltage will be present. Unless you're feeding some sort of electricity through it. I'm certainly not an electrical engineer, I do however use a volt/ohm meter occasionally. A volt/ohm meter is a dual/multi purpose piece of equipment.
If V in battery voltage equals 5volts Resistor 1 equals 6ohms and Resistor 2 equals 4ohms What will be the volt meter Vout read?
4.5 Volts
How do you read the value off a resistor?
Scroll down to related links and look at "Color Code Calculator - Resistor values with 4 and 5 color bands".
How calculated the value of resistor that is to be used in particular circuit?
To read the value of a resistor: Resistors are color coded, you can use the chart found below And how accurate the values of resistors are is their tolerance, also found in the chart
Why is a voltmeter used rather than a potentiometer?
A potentiometer is a variable resistor, while a voltmeter is a device that measures voltage.
What are resistor values defined by?
Resistor value is defined by the Resistance the resistor offers in Kilo ohms/ohms value given by color codes on the resistor.
What is type of resistor in edc labs?
those are the fixed resistor...u can't change their values..
What are the thermisters?
It's a resistor that changes values based on the temperature.
Where are resistor decade boxes commonly used?
designing circuits by semi-trial and error selection of the right resistor values.

How do you check resistor values in PCB?
using the color coding method
How do you read chip resistor?
Use a digital ohm meter as opposed to attempting to read the lettering on the chip. This will give you an immediate value that will fall within the tolerance of the chip resistor.
Why does the heater blower only work on high?
from what i have read it is the blower motor resistor it goes bad and only lets the fan run on high google blower motor resistor and read on
