What is the resistance for Black-Brown-Red-Gold?

Explanation:
Resistors use a color code where the first two bands are the digits, the third is the multiplier, and the fourth is tolerance. Black is 0 and Brown is 1, so the digits are 01, which is effectively 1. The multiplier red means multiply by 10^2 (100). So 1 × 100 equals 100 ohms. The gold band shows a tolerance of ±5%. Therefore, the resistance is 100 Ω.
