What is the resistance value of a resistor with the bands brown, black, and blue?

The resistance value of a resistor can be determined by interpreting the color bands according to the standard color coding system used for resistors. In this system, each color represents a specific digit or multiplier.

The first band, brown, corresponds to the digit 1. The second band, black, represents the digit 0. The third band, blue, is the multiplier, representing (10^6) or 1,000,000 (1 Mega ohm).

To calculate the resistance value, you combine the first two digits from the first two bands and then multiply by the value indicated by the third band. This gives you:

1 (from brown) followed by 0 (from black) gives you 10, and the blue band indicates that you multiply this by 1 Mega ohm. This results in:

[ 10 \times 1,000,000 = 10,000,000 \text{ ohms} ]

which is equal to 10 Mega ohms.

Therefore, the resistance value of this resistor is indeed 10 Mega ohms.
