The resistance of a carbon resistor of colour code Red-Red Green Silver is (in kΩ)

Options

(a) 2200±5%
(b) 2200±10%
(c) 220±10%
(d) 220±5%

Correct Answer:

2200±10%

Explanation:

Given, Colour coding of resistance = Red, Red, Green, Silver

First band value = 2

Second band value = 2

Third band value = 10⁵

Fourth band value = ± 10%

Now, R = 22 × 10⁵ ± 10% Ω

R = 2200 ± 10% kΩ
