A resistor is labeled 100 ohms with 5% tolerance. What is the range of possible actual resistance?

Explanation:
Resistors have a tolerance that indicates how much their actual resistance can differ from the labeled value. A 5% tolerance on a 100 ohm resistor means the resistance can vary by 5 ohms in either direction. So the actual resistance can be as low as 95 ohms or as high as 105 ohms, with the endpoints included. This is why the range is 95 ohms to 105 ohms.
