Determine the resistance value and tolerance of a resistor that has the following color bands; first band is red, second band is red, third band is orange, and the fourth band is gold A. 220 Ohm, 5% B. 220 Ohm, 10% C. 22,000 Ohm, 5% D. 22, 000 Ohm, 10% E. None of the above

[amp_mcq option1=”220 Ohm, 5%” option2=”220 Ohm, 10%” option3=”22,000 Ohm, 5%” option4=”22, 000 Ohm, 10% E. None of the above” correct=”option1″]

The correct answer is: A. 220 Ohm, 5%

The first band of a resistor indicates the first digit of its resistance value. The second band indicates the second digit of its resistance value, multiplied by 10. The third band indicates the number of zeros to be added to the resistance value. The fourth band indicates the tolerance of the resistor.

In this case, the first band is red, which indicates the number 2. The second band is also red, which indicates the number 2. The third band is orange, which indicates the number 10. The fourth band is gold, which indicates a tolerance of 5%.

Therefore, the resistance value of the resistor is 220 Ohms, with a tolerance of 5%.
