A resistor has bands with colours orange, green, silver and gold. Then, the resistance of the resistor is
- A \((350 \pm 5) \mathrm{m} \Omega\)
- B \((350 \pm 17.5) \mathrm{m} \Omega\)
- C \((35 \pm 5 \%) \mathrm{m} \Omega\)
- D \((250 \pm 5 \%) \mathrm{m} \Omega\)
Answer & Solution
Correct Answer
(B) \((350 \pm 17.5) \mathrm{m} \Omega\)
Step-by-step Solution
Detailed explanation
Given, orange \(=3\), Green \(=5\) Silver \(=10^{-2}\) Gold (tolerance) \(= \pm 5 \%\) From colour code, resistance value is \( \left[35 \times 10^{-2} \pm 5 \%\right. \text { ] } \)…
