0.25W resistors in the E12 series for all values between 10W and 1MW are kept plus the E6 range for values from 1W to 10W and from 1MW to 10MW. Resistor

There are also various values of high power resistors available from the technicians. Most of the resistors are marked with a colour code to show their value. You can use this calculator to find the value of a resistor if you know the colours. To find the colours if you know the value use this calculator.

Try Nick Reeder's colour code matching exercise and Nick Reeder's resistor recognition game (check out Nick Reeder's pages at Sinclair College, Dayton, Ohio, USA).
