Brown, Red and Orange coloured bands on a carbon resistor are followed by Silver band. The value of resistor is ________.
- A \(320 \Omega \pm 5 \%\)
- B \(12 k \Omega \pm 5 \%\)
- C \(320 \Omega \pm 10 \%\)
- D \(12 k \Omega \pm 10 \%\)
Answer & Solution
Correct Answer
(D) \(12 k \Omega \pm 10 \%\)
Step-by-step Solution
Detailed explanation
(D)
As per colour code
\(
\begin{array}{ll}
\text { Brown } \rightarrow 1 \\
\text { Red } \rightarrow 2 \\
\text { Orange } \rightarrow 10^3 \\
\text { Silver } \rightarrow 10 \% \\
\text { resistance } R=\left(12 \times 10^3 \pm 10 \%\right) \Omega \\ R=(12 k \Omega \pm 10 \%)\end{array}\)
