Q. A colour coded carbon resistor has the colours orange, blue, green and silver. Its resistance value and tolerance percentage respectively are
A) $36 \times 10^{5}\Omega$ and 10%
B) $36 \times 10^{4}\Omega$ and 5%
C) $63 \times 10^{5}\Omega$ and 10%
D) $35 \times 10^{6}\Omega$ and 5%
Explanation
(a) First colour gives first digit, second colour gives second digit and third colour gives the multiplier and fourth colour gives the tolerance
