In the resistor color code Brown-Black-Red-Gold, what is the resulting resistance value and tolerance?

Explanation:
Resistor color codes use bands to spell out the value. The first two bands are the significant digits: brown is 1 and black is 0, giving 10. The third band is the multiplier: red means multiply by 100, so 10 × 100 = 1000 ohms, which is 1 kΩ. The fourth band indicates tolerance: gold equals ±5%. So the resistor is 1 kΩ with a ±5% tolerance.
