Ohm’s Resistor by WebSpinner, LLC
Compute Voltages, Resistance, or Amperage in a touch with Ohm’s Resistor! Not just the resistance value like other resistance calculators.
Need a resistor? Simply enter a desired voltage, the current drawn, as well as the supplied voltage, and Ohm’s resistor will tell you what kind of resistor you need.
Do you need to know how much of a voltage drop is produced by a certain resistor in a circuit? Enter the Amps drawn and the voltage in, as well as the resistor value, and Ohm’s resistor will tell you.
Calculate Voltage In, Voltage Out, Resistance or Current instantly by entering the appropriate values. The selected field is updated instantly when you enter a value. Change the resistor value by simply touching a band and the selected value will be updated to match the new resistor value.
