# Practical resistors

### Explanation of question 2

A resistor has a nominal value of 33k and an actual value of 29k. The resistor is within

1. 10% of its quoted value, but high
2. 10% of its quoted value, but low
3. 20% of its quoted value, but high
4. 20% of its quoted value, but low

The answer is :- 4 33k ± 10% is 29.7k to 36.3k. 33k ± 20% is 26.4k to 39.6k. The actual value, 29 k, is outside the 10% tolerance, but within the 20% tolerance. It is of low value.
