Question

The colour coding on a carbon resistor is shown in the given figure. The resistance value of the given resistor is

• A. $(7400\pm 740\Omega )$
• B. $(3700\pm 185)\Omega$
• C. $(7400\pm 370\Omega )$
• D. $(3700\pm 370)\Omega$

Answer 1

The correct option is B $(3700\pm 185)\Omega$

$R=37\times {10}^2\pm 5\%$
$=(3700\pm 185)\Omega$
