To identify the value of a carbon resistor using colour code use the following table...
0 - Black
1 - Brown
2 - Red
3 - Orange
4 - Yellow
5 - Green
6 - Blue
7 - Violet
8 - Grey
9 - White
... and look at the bands. The first two bands will be the digits, and the third band will be the multiplier. For instance, Brown - Red - Orange will be 12000 ohms, where the 1 is the first band, the 2 is the second band, and the three 0's is the third band.
If the third band is Gold or Silver, then the multiplier is 0.1 or 0.01 respectively. For instance, Brown - Red - Gold would be 1.2 ohms, and Brown - Red- Silver would be 0.12 ohms.
If there is no fourth band, the resistor is +/- 20%. If the fourth band is Silver, the resistor is +/- 10% and, for Gold, +/- 5%.
Some high end resistors have more bands. The 1% resistor will have a third digit band, and some resistors will have a band indicating temperature coefficient.
Hi You can find the value of the resistor by using colour code printed on the resistor. 1. Hold the resistor such that the colour code starts from left. 2. Each of the colour bands present on the resistor specifies a value. 3. The first colour band represents the first significant figure, the second band represents the second significant figure and the third band indicates the multiplier. The fourth band represents the tolerance. Gold band- 5%, Silver band-10%, No band-20% 4.Find the appropriate values for the colour by using the chart 1. 5. Find the value of the resistor by using the formula 1. Chart1 Example: Here first band represent brown. Second band represent black. Third band represent red . Fourth band represent gold. The value of resistor = 10 x 102 ± 5% = 1kΩ ± 5%

A variable resistor means that the resistance can be varied, usually by using a slide. A fixed resistor can not be varied.
It depends on where you are going to use this resistor and what its application going to be. If the circuit you are using can tolerate this then you are fine.
The function of a neutral earth resistor is to limit any fault current resulting from fault between a line conductor and earth.

Tolerance indicates how much the measured value of a resistance is different from its theoretical value, and it is calculated using percentages.
Resistor
count up the value of the resistor using the colour bands along with resistor code chart(or it may on the resistor eg. 10kohms, follow this by hooking up an ohm meter(you will have to select ohms, kilo-ohms, mega-ohms whichever applies) , your resistance should appear within the acceptable variable guidelines.. usually 5 to 10 percent(last band or on the resistor itself) count up the value of the resistor using the colour bands along with resistor code chart(or it may on the resistor eg. 10kohms, follow this by hooking up an ohm meter(you will have to select ohms, kilo-ohms, mega-ohms whichever applies) , your resistance should appear within the acceptable variable guidelines.. usually 5 to 10 percent(last band or on the resistor itself)
using a variable resistor we can adjust the sensitivity of a light dependent resistor
if you want to find the current (in amperes) through the resistor then connect a ammeter in series with the resistor.
A variable resistor means that the resistance can be varied, usually by using a slide. A fixed resistor can not be varied.
yes you can! you can use a multimeter and a resistor.
To prevent using as potable water.
first see if you can identify its type. then see if you san exract dna. check its age by using carbon-14 scans.
No, Using a resistor spark plug with resistor wires can create too much resistance for the ignition system.
It depends on where you are going to use this resistor and what its application going to be. If the circuit you are using can tolerate this then you are fine.
