Question 156Electricity & Electronics - 1st Asst/Chief

The correct answer is B) green, black, black, and gold. This is correct because the color bands on a resistor follow a standard color coding system that indicates the resistor's resistance value and tolerance. For a 50-ohm resistor with a 5% tolerance: - The first band is green, which represents the first digit of the resistance value (5). - The second band is black, which represents the second digit of the resistance value (0). - The third band is black, which represents the multiplier (x1 or 10^0). - The fourth band is gold, which represents the tolerance of 5%. The other options are incorrect because they do not match the proper color coding for a 50-ohm, 5% tolerance resistor.
