Color codes • Each resistor has either 4 or 5 bands. In the 4

band type, the first two bands indicate the first two digits of the value while the third one indicates the number of zeros that follow, the last band specifies the tolerance: in the example below gold indicates that the resistor value can be 10k ohm or minus 5%

Write out an example calculation to find the # of Amps of your circuit (use

Ohm's law)When I was making my circuit, the circuit supplied 5 volts the resistor supplied 220 ohms of resistance. To find the number of amps of your circuit you will need to divide 220 by 5 which will give you .023. This will give you 23miliamps.

Show me the colour code for your chosen resistor.

• The resistor that I have chosen for my circuit has 4 bands the colour code is red, red, brown, and gold. The first bands digit is 2 the second digit is also 2 the third digit which is also a multiplier is one which makes 220 the last band is called tolerance which is 5%
