Examples for

Resistors

Resistors are common electrical components that impede an applied electric current. Use Wolfram|Alpha to compute the resistance of resistors in parallel and series. Translate resistor color codes to and from resistance values.

Color Codes

Translate resistor color codes into resistance and back.

Calculate the color code for a resistor:

7500 ohm resistor

Compute resistance from resistor color codes:

resistor black red green silver

Resistors in Parallel & Series

Calculate total resistance for resistors in parallel and series.

Compute resistance for resistors in parallel:

parallel resistors 30ohm, 60ohm

Compute resistance for resistors in series:

series resistors 20ohm, 50ohm
