A carbon film resistor has colour code Green Black Violet Gold. The value of the resistor is
- A \( 50 \mathrm{M} \Omega \)
- B \( 500 \mathrm{M} \Omega \)
- C \( 500 \pm 5 \% M \Omega \)
- D \( 500 \pm 10 \% M \Omega \)
Answer & Solution
Correct Answer
(C) \( 500 \pm 5 \% M \Omega \)
Step-by-step Solution
Detailed explanation
Given, colour code on resistor is
Green \(-5\); Black \(-0\); Violet \(-7\); Gold \(-5 \%\)
First and second band corresponds to digit, third band corresponds to multiplier and fourth band corresponds to tolerance. Therefore, the value of resistor i
\(50 \times 10^{7} \pm 5 \% \Omega=500 \times 10^{6} \pm 5 \% \Omega\)
\(=500 \pm 5 \% \mathrm{M} \Omega\)
Green \(-5\); Black \(-0\); Violet \(-7\); Gold \(-5 \%\)
First and second band corresponds to digit, third band corresponds to multiplier and fourth band corresponds to tolerance. Therefore, the value of resistor i
\(50 \times 10^{7} \pm 5 \% \Omega=500 \times 10^{6} \pm 5 \% \Omega\)
\(=500 \pm 5 \% \mathrm{M} \Omega\)
