## Standard Resistor ValuesResistors are one of the four fundamental types of passive electronic components; the other three are the inductor, the capacitor, and the memristor. The basic unit of resistance is the ohm (Ω). - Resistor and Capacitor Color Code Charts

Standard base resistor values are given in the following tables for the most commonly used tolerances (1%, 5%, 10%), along with typically available resistance ranges. To determine values other than the base, multiply the base value by 10; 100; 1,000; or 10,000.
Standard resistor values are calculated using the simple formula given below. Round the results to the proper number of significant figures (3 for 1% and 2%, 2 for 5% and 10%). As the chart at the right shows (created in Excel), plotting the values on a logarithmic scale results in a straight line.
