Detailed explanation-1: -A resistor’s first three colour bands are brown, green and red. its value is 1500 ohms. * True False 2.
Detailed explanation-2: -EXAMPLE: Brown, Black, Red = 1000 Ohms not Black, Brown, Orange as this calculator will display as 1000 Ohms. The fourth band is a TOLERANCE band.
Detailed explanation-3: -The values of 3-band resistors have a tolerance of ±20% and are commonly used by hobbyists or when the resistance value is not critical. For a 1R0 (1 ) resistor with 3 bands, the colors will be brown, black and gold. The resistance value will fall between 1.2 and 0.8 .
Detailed explanation-4: -A 1M Ohm resistor can be identified via resistor color codes of Brown-Black-Green-Gold or Brown-Black-Black-Yellow-Gold.
