This tool will convert voltage to current for you based on the power rating you provide.
Volts to Amps Calculator
This simple calculator allows you to convert voltage (in volts) to current (in amps) by using Ohm’s Law, which states that the current in a circuit equals the voltage divided by the resistance.
How to Use
- Enter the voltage (in volts) into the “Voltage” field.
- Enter the resistance (in ohms) into the “Resistance” field.
- Click the “Calculate” button to see the result in amps displayed in the “Result” field.
How it Works
Ohm’s Law is expressed as: I = V / R
Where: I = current in amps, V = voltage in volts, and R = resistance in ohms.
The calculator performs this calculation for you. Simply input your voltage and resistance values to get the current.
Limitations
- The calculator assumes a linear response and does not account for non-linear components.
- Resistance must be greater than zero.
- Invalid or missing inputs will result in an “Invalid Input” message.
