The resistor resistance value on the figure is …
Solusan:
The first two colors represent the first two numbers of the resistance value, the third color represents the tenth power used to multiply, and the fourth color represents the tolerance of deviation.
The first color = red = 2
The second color = orange = 3
The third color = brown = 101 = 10
The fourth color = gold = 5%
The resistor value is 230 Ω with a deviation of 5% x 230 Ω = 11.5 Ω. If there is a change in temperature, the minimum resistance is 230 11 – 11.5 Ω = 218.5 Ω and the maximum resistance is 230 Ω + 11.5 Ω = 241.5 Ω.

What is the value of the resistor resistance in the figure?
Solusan:
The first color = brown = 1
The second color = black = 0
The third color = blue = 106 = 1000,000
The fourth color = gold = 5%
The resistor value is 10,000,000 .000 with a deviation of 5% x 10,000,000 Ω = 500,000 Ω. If there is a change in temperature, the minimum obstacle is 10,000,000 500 – 500,000 Ω = 9,500,000 Ω and the maximum obstacle is 10,000,000 Ω + 500,000 Ω = 10,500,000 Ω.
