A resistor is marked with the colour bands green, blue, brown and silver (in order). What is its resistance and tolerance?

56 ohm +- 5%
560 ohm +- 10%
560 ohm +- 5%
5600 ohm +- 10%

Correct answer: 560 ohm +- 10%

Solution

Green(5) blue(6) gives 56, brown multiplier 10¹ gives 560 ohm, silver tolerance +-10%.
