Question

The difference between the maximum and minimum values of resistance of a resistor with the color scheme green-green-red-silver is

• A. $55\, \Omega$
• B. $1100 \, \Omega$
• C. $44\, \Omega$
• D. $440 \, \Omega$

Answer 1

Answer: (B)

$1100 \, \Omega$

Answer 2

Color scheme:Green - green - red - silver
$\therefore R=(5.5 \times 10^{3} \pm 10\%)$
$\Omega=(5500 \pm 10\%)\, \Omega$
$R_{min}=(5500-550)$
$\Omega =4950\, \Omega$
$R_{max}=(5500+550)\, \Omega$
$=6050\, \Omega$
$\therefore R_{max}-R_{min}=6050-4950$
$=1100\, \Omega$
