A resistor with a black, black, and red color code has what resistance value?

The resistance value of a resistor can be determined using the color code method for resistors. In this case, the colors black, black, and red correlate to the numerical values of the digits used to form the resistance value.

Black represents the number 0, and since this color appears twice, it indicates the first two digits of the resistance value are both 0. The third color, red, represents the multiplier of 100. Therefore, the calculation for the resistor's value is as follows:

• The first digit (black) is 0.

• The second digit (black) is 0.

• The multiplier (red) is 100.

So, the resistance value is calculated as:

0 (first digit) 0 (second digit) followed by multiplying by 100, which results in 0 ohms (0 * 10^2 = 0).

Thus, the correct answer indicates that the resistor has a resistance value of 0 ohms. This means it acts effectively as a short circuit in a given electrical circuit, allowing current to pass without resistance.
