Answer:
22×100 plus or minus 5% // 22×10^2 +_ 5%
Explanation:
According to the given question, the resistor has 3 bands of same colour i.e, red with gold as 4th band.
We know that by looking at the colour of bands at the resistor we determine its resistance.
The following chat can help you to see how we write the resistance of a resistor by using colours.
1st colour -- 1st digit
2nd colour -- 2nd digit
3rd colour -- Multiplier
4th colour -- tolerance
And from the given data we can say that its resistance is,
- Resistance = 22×10^2 +_ 5% ans.
If there are 5 bands then we have to take 3rd digit which was not in 4 band resistor. It can go up to 6 bands resistor.
