Question

The colour coding on a resistor from the left are blue, yellow, red and silver as shown in figure. The value of resistance is

• A. $6400\Omega \pm 20$
• B. $6400\Omega \pm 10$
• C. $4600\Omega \pm 10$
• D. $6400\Omega \pm 5$

Answer 1

The correct option is B $6400\Omega \pm 10$


Blue : $6$ ; Yellow : $4$ ; Red : $2$ ; Silver : $10\%$

$\therefore \text{Resistance}R=64\times {10}^2\Omega \pm 10$

$\text{(i.e)}R=6400\Omega \pm 10$
