Front

How many color bands are typically found on a resistor? Options: 4 or 5, 2 or 3, 8 or 9, 6 or 7

Back

4 or 5

Front

What is the purpose of the color code on resistors?

Back

To indicate resistance value and tolerance

Front

If a resistor has the color bands: red, red, brown, gold, what is its resistance value?

Back

220 ohms with a tolerance of ±5%.

Front

A resistor has the color bands: yellow, violet, orange, silver. What is its resistance value?

Back

Front

Explain how to read the resistance value of a resistor using the color code.

Back

Identify the color bands on the resistor, match each color to its corresponding number from the color code chart, then use the significant digits, multiplier, and tolerance to calculate the resistance value.
