User Guide

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

Formula

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

I = V / R

Symbols

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

Voltage (V)

This is the DC voltage or electrical potential difference applied to or generated by the electrical circuit with the entered values for current and resistance.

Resistance (R)

This is the electrical resistance of the DC electrical circuit

Current (I)

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