A resistor is banded brown, black, red. What is its resistance?

Correct answer to question 30 (Electronics Information): 1,000 ohms

Method

Brown is 1 and black is 0, giving the digits 10. Red as the third band means multiply by 100, so 10 x 100 = 1,000 ohms. Reading the third band as a digit rather than a multiplier gives 102.
