Question

A carbon resistor has bands of different colours on its body as mentioned in the figure. The value of the resistance is ?

• A. $2.2k\Omega$
• B. $3.3k\Omega$
• C. $5.6k\Omega$
• D. $9.1k\Omega$

Answer 1

The correct option is D $9.1k\Omega$

Code of white$=9$

Code of brown $=1$

Code of red $=2$

Code of silver $=10\%$ $tolerance$

So, $R=91\times {10}^2=9.1k\Omega$

The value of resistance is $9.1k\Omega$

The correct option is D.
