Question

The colour code of a carbon resistor is given below.

The value of resistance with tolerance is given as

• A. $(4.2\text{k}\Omega \pm 5\%)$
• B. $(4.2\text{k}\Omega \pm 10\%)$
• C. $(4.3\text{k}\Omega \pm 10\%)$
• D. $(2.4\text{k}\Omega \pm 5\%)$

Answer 1

The correct option is A $(4.2\text{k}\Omega \pm 5\%)$

$\text{Yellow}\to 4$
$\text{Red}\to 2$
$\text{Gold}\to 5\%$
$R=(42\times {10}^2\pm 5\%)\Omega R=(4.2\text{k}\Omega \pm 5\%)$
