Current Calculator

To calculate the current in an electrical circuit, you need to know a few key parameters. By entering the voltage, resistance, or power, you can easily determine the current flowing through the circuit using basic formulas.

You need any of these two parameters for the calculation:

1. Voltage (V): The potential difference or voltage across the circuit, typically provided by the power source (in volts).

2. Resistance (Ω): The resistance in the circuit, which opposes the flow of current, usually specified for the components (in ohms).

3. Power (W): The power consumed by the circuit, which can be derived from the voltage and current (in watts).
