Question

The carbon resistor has three orange bands. The maximum value of resistance offered by the resistor will be __________.

• A. $39.6k\Omega$
• B. $49.6k\Omega$
• C. $33k\Omega$
• D. $26.4k\Omega$

Answer 1

The correct option is C $33k\Omega$

The resistance can be calculated with a help of the colour coding chart.

The colour of the first band indicates the first significant figure, the colour of the second band indicates the second significant figure and the colour of the third band indicates the multiplier to be used.

Thus, the resistance of a carbon resistor with three orange bands would be:

3 (orange) 3(orange) x 1000 (orange) = 33,000 ohms

The maximum value of resistance $=33\times {10}^3\Omega =33k\Omega$
