Question
What is the resistance of the following resistor?
- 45 Ω ±20%
- 46 Ω ±20%
- 54 Ω ±20%
- 56 Ω ±20%
Hint:
The resistance is 45 Ω ±20%
The correct answer is: 45 Ω ±20%
- A resistor is an electrical component with two terminals which implements electrical resistance in a circuit.
- The colour codes are used as a symbol to specify the reliability and tolerance of a resistor.
Yellow band = 4 Green band = 5 black multiplier =1 tolerance = 20%
