Front

How do you determine the value of a resistor using color codes?

Back

By reading the colors from left to right, where each color corresponds to a number and the last color indicates tolerance.

What does the gold band on a resistor indicate?

Back

A tolerance of ± 5%.

Front

What does the silver band on a resistor indicate?

Back

A tolerance of ± 10%.

Front

What is the significance of the first two color bands on a resistor?

Back

They represent the first two significant digits of the resistor's value.
