Answer:
A carbon composition resistor having only three color stripes has a tolerance of 20 percent .
A resistor would normally have four color codings, with the fourth color indicating tolerance. A resistor having no band at all would mean a 20% tolerance.
What is Tolerance of Resistor
Tolerance of resistors means/indicates the amount of deviation or changes a resistor can take and still operate within allowable limits.
There are several types of Resistor
- Fixed Value Resistors
- Variable Resistors
- Resistor Networks
- Carbon Film Resistors
- Metal Film Resistors
- Wire wound Resistors
- Metal Oxide Resistors
- Metal Strip Resistors
