The value of the resistance is expressed as a number of ohms (the symbol Ω is used for ”ohm”). In this lesson, we work this out for a 1k Ω resistor where ”k” is the abbreviation for the prefix ”kilo”, meaning 1000. So, a 1k Ω resistor has a value of 1000 ohms and the number we will code is 1000.

If I understand your question, then yes – resistors are reversible, in the sense that they can be connected to the circuit in either direction. Resistors are not like diodes or capacitors. They do not have a polarity. The conduct (or resist) current equally in both directions of current flow.
How do you determine the value of a resistor?
Position the resistor with the gold or silver color band to the right..
Read the color sequence that must be decoded to determine resistance.
Determine the coded number for the resistive value.
Determine the tolerance of the resistor.
Determine the decoded number for the resistive value.
Orient the resistor so you can read the stripes properly. You should read the stripes from left to right. The first stripe is the one that’s closest to one end of the resistor. If this stripe is on the right side of the resistor, turn the resistor around so the first stripe is on the left.
How do you test a resistor?
Remove power from the circuit containing the resistor.
Isolate the resistor from the circuit.
Inspect the resistor.
Read the resistor value visually.
Prepare a digital multimeter (DMM) to measure the resistor.
Measure the resistance.
Determine the actual resistance of the resistor.
What is meant by the tolerance of a resistor?
“Tolerance is the percentage of error in the resistor’s resistance, or how much more or less you can expect a resistor’s actual measured resistance to be from its stated resistance. A gold tolerance band is 5%tolerance, silver is 10%, and no band at all would mean a 20% tolerance.” Source: Resistor Color Codes.
