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

Red — Red corresponds to the digit 2 in the color code.

Q: What is the color code for the multiplier '1000'?

Orange — Orange represents a multiplier of 1000 (1k).

Q: What is the tolerance of a gold band resistor?

±5% — Gold represents a tolerance of ±5%.

Q: What is the tolerance of a silver band resistor?

±10% — Silver represents a tolerance of ±10%.

Q: What color represents the digit '0'?
