Question:

The resistance of a carbon resistor if the colour code from left to right indicates brown, yellow, green and gold.

 

Options:

$(1.4 ± 0.07)M\Omega$

$(0.7 ± 0.14)M\Omega$

$(1.8 ± 0.09)M\Omega$

$(1.6 ± 0.08)M\Omega$

Correct Answer:

$(1.4 ± 0.07)M\Omega$

Explanation:

using the diagram for colour code 

$R = 14 \times 10^5 \pm 5 \% = (1.4\times 10^6 \pm 0.07 \times 10^6 )\Omega = (1.4 ± 0.07)M\Omega$
