Resistor Color Code: Fundamental Identification…

Q: Which color represents the value '0' in the resistor color code?

Black — Black is always '0' in the standard resistor color code.

Q: What is the color code for the number '2'?

Red — Red corresponds to the value '2' in the resistor color code.

Q: What does the third color band in a 4-band resistor represent?

Multiplier — The third band indicates the power of ten by which the first two digits are multiplied.

Q: Which color is often used to represent a tolerance of 5%?

Green — Green band typically denotes a 0.5% tolerance. Gold is often used, for 5%

Q: What does the fourth band on a 4-band resistor usually indicate?

Tolerance — The fourth band (if present) indicates the resistor's tolerance.

Q: If a resistor has the color bands Brown, Black, Red, Gold, what is its resistance value?

1000 ohms ± 5% — Brown=1, Black=0, Red=x100, Gold=5%. Therefore, 10 * 100 = 1000 ohms, 5% tolerance

Q: What color represents the multiplier of x1000 in the resistor color code?

Orange — Orange represents a multiplier of x1000 or 10^3 in the standard code.

Q: What color represents the tolerance of 10%?

Silver — Silver represents a tolerance of 10% in the resistor color code.

Q: What is the value represented by a yellow band?

4 — Yellow represents the value 4 in the resistor color code.

Q: Which band signifies the first significant figure in a resistor code?

1st Band — The first color band indicates the first digit.
