Question:

If the four colours of the bands in a carbon resistor are orange, blue, yellow and gold, the resistance value is:

Options:

$(3.6 × 10^5)±20\%Ω$

$(63 × 10^4)±10\%Ω$

$(3.6 × 10^4)±5\%Ω$

$(36 × 10^4)±5\%Ω$

Correct Answer:

$(36 × 10^4)±5\%Ω$

Explanation:

The correct answer is Option (4) - $(36 × 10^4)±5\%Ω$

(1) First Band (Orange): Represent the first digit 3.

(2) Second Band (Blue): Represent the Second digit 6.

(3) Third Band (Yellow): Represent the multiplies $10^4$.

(4) Fourth Band (Gold): Represent the tolerance ± 5%

Resistance = 36 × 10,000 Ω = 360 kΩ

and, tolerance = 5%

∴ 360 kΩ± 5%Ω
