Let’s take an example of a 5-band resistor with the colors given in the above image (brown, green, red, black and gold). So according to the formula the resistance will be: 152 * 1 = 152 Ohms with 5% ...
Let’s take an example of a 4-band resistor with the colors given in the above image (brown, blue, red and gold). So according to the formula the resistance will be: 16 * 100 = 1600 Ohms or 1.6K Ohms ...
