resistor
Resistors "resist" the flow of electrical current. The higher the value of resistance (measured in ohms) the lower the current will be.
Resistors are color coded. There are three color bands, one multiplier band, and one tolerance band. To read the color code of a common 4 band 1K ohm resistor with a 5% tolerance, start at the opposite side of the GOLD tolerance band and read from left to right. Write down the corresponding number from the color chart below for the 1st color band (BROWN). To the right of that number, write the corresponding number for the 2nd band (BLACK) . Now multiply that number (you should have 10) by the corresponding multiplier number of the 3rd band (RED)(100). Your answer will be 1000 or 1K. It's that easy.
