JEE · NEET Previous Year Question

$A resistor has a colour code of green, blue, brown and silver. What is its resistance?$

Topic: JEE PYQ

Answer: B. Full step-by-step solution below.

A $56Ω \pm 5 %$
B $560Ω \pm 10 %$
C $560Ω \pm 5 %$
D $5600Ω \pm 10 %$

Correct answer: B

Solution

(b) Numbers attached for green, blue, brown and silver are 5, 6, 1 and 10 % . Therefore, the resistance of a given resistor = 56 \times 10^{1} Ω \pm 10 % = 560Ω \pm 10 %
