A resistor with a 100 ohms of resistance has 10% tolerance. What does this mean?
The resistance may vary from 90 ohms to 110 ohms.
The resistor has a fixed resistance of 100 ohms.
The resistance may vary from 90 ohms to 100 ohms.
The resistance may vary from 100 ohms to 110 ohms.
Detailed Explanation
Tolerance of a resistor indicates how much the measured value of a resistance is different from its theoretical value, and is calculated using percentages. 10% tolerance means that the resistance can be more or less 10 ohms to compare with 100. A 100 ohms resistor with 10% tolerance may have values ranging from 90 ohms to 110 ohms.
