A carbon resistance has a following colour code. What is the value of the resistance?

Figure

Show answer and solution

Answer: (a)

  1. Green = 5, Orange = 3, Yellow = multiplier 10410^4, Gold = ±5%\pm 5\%.
  2. R=53×104=530 kΩR = 53 \times 10^4 = 530\text{ k}\Omega
  3. So the answer is (a) 530 kΩ±5%530\text{ k}\Omega \pm 5\%.
