Practice using the standard resistor color code digits from 0 through 9 to identify and create resistor band patterns.
Use the resistor color code digit chart: black = 0, brown = 1, red = 2, orange = 3, yellow = 4, green = 5, blue = 6, violet = 7, gray = 8, white = 9. Read each problem carefully and show your work in the space provided.
Practice matching resistor color bands to digit values
Physics - Grade 9-12
- 1
A resistor has a first band that is red and a second band that is green. What two-digit number do these bands represent?
- 2
Write the color code digit for each color: black, yellow, blue, and white.
- 3
A resistor begins with the bands brown and black. What two-digit number is shown by these first two bands?
- 4
Which two colors would you use for the first two bands of a resistor if you wanted to show the number 47?
- 5
A student says that orange = 4 and yellow = 3. Explain the mistake and give the correct values.
- 6
A resistor has first and second bands gray and red. What two-digit number do these bands represent?
- 7
Complete the missing values in this sequence of resistor color digits: black = 0, brown = 1, red = 2, orange = 3, yellow = 4, green = __, blue = __, violet = __, gray = __, white = __.
- 8
Which first two resistor bands would represent the number 09?
- 9
A resistor shows the first two bands violet and brown. Another resistor shows the first two bands brown and violet. Do they represent the same number? Explain.
- 10
Make a two-column table that lists each digit from 0 through 9 and its resistor color code.
- 11
A resistor has first and second bands green and orange. What two-digit number do the bands represent, and which band gives the tens digit?
- 12
Choose the correct color pair for the number 68: blue and gray, blue and orange, green and gray, or violet and black. Explain your choice.
