Calculation Formula

I = V / R

Where:
I = Current (Amperes)
V = Voltage (Volts)
R = Resistance (Ohms)

Learn how to use the Voltage to Current Ratio Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the voltage (V) in volts in the first input field.
  2. Enter the resistance (R) in ohms in the second input field.
  3. Click the "Calculate" button to compute the current (I).
  4. The result will be displayed in the current (I) field.

Working Principle

This calculator uses Ohm's Law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. The formula is:

I = V / R

Where:

  • I = Current (Amperes)
  • V = Voltage (Volts)
  • R = Resistance (Ohms)

Example

If you have a circuit with a voltage of 12 volts and a resistance of 6 ohms, the current would be:

I = 12 V / 6 Ω = 2 A

This means that 2 amperes of current will flow through the circuit.
