What is the purpose of the color bands on a fixed resistor?
The colour bands indicate the value and tolerance of the part. The colours are specified in in standards published by the "Radio Manufactures Association" in North America. One (of many) handy pages that help explain how to read the code is here : http://www.radioremembered.org/rescode.htm . There are many other similar pages out there.

Can a fixed resistor be used as a dimmer in a lighting circuit and if no what can be?
No. A fixed resistor cannot be used as a dimmer in a lighting circuit. Depending on the dimming setting, you would need to dissipate substantial power across the resistor. What you need instead is some kind of pulse width modulated device, such as an SCR or TRIAC, or switching power supply, that does not dissipate a lot of power when it is turned on, because it operates in saturated mode, but the average power delivered to the load is what you want it to be.
Pioneer a335 amplifier and the volume control resistor has broke i am woundering since they don't sell it no more what the equvilant of the resistor act1047 is?
If you cant find a spec sheet, take out a multi meter, set it to ohm mode and measure the thing. If its a variable find something in the same range, if its fixed you should be able to find a suitable replacement. If its a big resistor make sure you get a power resistor and not a standard ceramic one.
In a series circuit each device that is added to the circuit decreases the what?
Depends on the device. If it is a resistor and you have a fixed voltage then the circuit will obey Ohms law. Voltage = Current x Resistance. So if R increases by adding more resistors in series and the voltage is constant, the current will decrease.
Why are fixed resistors values indicated by colors?
Because the actual resistor is too small to print numbers, so color bands and math are used instead. I just don't know how to calculate the values.

What is the difference between a fixed resistor and a variable resistor?
its the colour of the fixed and the variable we define it by its power and name

Difference between variable and fixed resistor?
Variable resistors means that a resistor which can change its resistance by control by any person or it self and fixed resistor means that it can not change its value.
What is the function of fixed resistor?
To limit the current
Does a variable resistor have a bias?
A variable resistor means that the resistance can be varied, usually by using a slide. A fixed resistor can not be varied.
What is type of resistor in edc labs?
those are the fixed resistor...u can't change their values..
What is a fixed resistor measured in?
Resistance is measured in ohms.
What would you expect if resistance of the fixed resistor was zero?
zero
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.

What is the purpose of fixed resistor?
To lower the voltage and amperage in order to better fit the needs of other components.
