Question

A given resistor has the following colour code of the various strips on it : Brown, black, green and silver. The value of its resistance in ohm is

• A. $1.0\times {10}^4\pm 10\%$
• B. $1.0\times {10}^7\pm 5\%$
• C. $1.0\times {10}^6\pm 10\%$
• D. $1.0\times {10}^5\pm 5\%$
• E. $1.0\times {10}^3\pm 10\%$

Answer 1

Answer: (C)

$1.0\times {10}^6\pm 10\%$

The number for brown colour is 1, for black is 0 and that of green is 5.

For silver, tolerance is 10 %

$\therefore$ the value of given resistor is

$R=10\times {10}^5\pm 10$% ohm

$R=1.0\times {10}^6\pm 10$ % ohm
