19. A red, red, orange, gold resistor has a nominal value of ________.

(a) 22,000 Ω
(b) 2,200 Ω
(c) 22 Ω
(d) 2.2 Ω

Explanation
Explanation :

Red: 2
Red: 2
Orange: 3
Gold: 5% tolerance.

Resistor is : 22 * 10^3 = 22,000 ± 5% ohm.

BLACK: 0
BROWN: 1
RED: 2
ORANGE: 3
YELLOW: 4
GREEN: 5
BLUE: 6
VIOLET: 7
GREY: 8
WHITE: 9

GOLD: 5% (tolerance)
SILVER: 10%  (tolerance)
NO COLOUR: 20% (tolerance)

The first band gives the first digit.
The second band gives the second digit.
The third band indicates the number of zeros.
The fourth band is used to shows the tolerance (precision) of the resistor.

Short trick of colour bands:
B B R O Y G B V G W.
