How do you find a resistor?
To calculate the total overall resistance of a number of resistors connected in this way you add up the individual resistances. This is done using the following formula: Rtotal = R1 + R2 +R3 and so on.
What is tolerance resistor?
Tolerance Band 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.

What does a 2.2 K ohm resistor look like?
Thus, for 2.2k ohm resistor, 1st digit is ‘ 2 ‘, ∴ look for color in a chart with value 2, then it’s your 1st color(say red). The next 2nd digit is ‘ 2 ‘, ∴ look for color in a chart with value 2, then it’s your 2nd color (say red). The last bands in 4/5 th bands resistors shows the tolerance value of the resistor.
What is a bad resistor?
A resistor is in place to restrict current. A faulty resistor is most likely an over-current issue somewhere in the circuit. The constant heating and cooling can take its toll. A fuse can blow for multiple reasons, its primary function is circuit protection.
Do resistors go bad?
Resistors don’t really go bad unless you physically damage them or burn them by applying too much power. In that case, they have a very unique smell. The odor is hard to describe, but you’ll know something’s not correct.
How do identify resistor values?
First Step. The Red band of the resistance value is 2 and the brown band of the resistance value is 1 from the table. Second Step. From the table, the third orange band has value 1000. Multiply this value to 21 i.e. Third Step. Last is the Gold band having tolerance value in 5% (0.05) from the table.
How do you test a ballast resistor?
Mopar Ballast Resistor Test. Using an electrical multi-meter, check the resistance between the noted terminals of the ballast resistors. Do this with all of the wires to the ballast resistor disconnected. Any significant deviation from these numbers would indicate that the ballast resistor is defective.
