User Guide

Use this calculator to determine the electrical resistance in ohm, kilohm, or megohm units of a direct current (DC) electrical circuit with a specified voltage and current. Two conversion scales show how the resistance of an electrical circuit changes as voltage or current is changed independently whilst keeping the other constant.

Formula

The formula used by this calculator to determine the DC electrical resistance of a circuit from the voltage and current is:

R = V / I

Symbols

  • R = Electrical resistance (DC)
  • V = Voltage (DC)
  • I = Current (DC)

Voltage (V)

This is the DC voltage or electrical potential difference applied to or generated from the electrical circuit.

Current (I)

This is the electrical current flowing through the DC electrical circuit.

Resistance (R)

This is the electrical resistance of the DC electrical circuit with the entered values for voltage and current.
