A resistor with the color bands brown, red, red and silver will have a resistance of a. 120 ohms b. 1200 ohms C. 2100 D. 6,400

1.2 Kilo ohms with 10% tolerance.

Answer: b) 1200 ohms

Explanation:

There is a color code given to the carbon resistors as their size is very small to mark the value on it. These resistors have bands of the color in which the first band of the color describes the value before the decimal place and the color after the first color and before last second color are of the values after the decimal place and the last color is of the tolerance of the resistor also the last second color is of the multiplier to the value comes from previous color bands. These values are already fixed for each color according to the resistance color code chart and are easy to understand.

1200+_10%

Explanation:

The first two bands reresents the first two digits of the resistance value in ohms. This multiplier will shift the decimal place around to change the value from mega ohms to milliohms and anywhere in between. The fourth color band signifies tolerance. Giving a total of
