This calculator helps you determine the relationships between electrical power (watts), voltage (volts), current (amps), and resistance (ohms) in electrical circuits. It's based on Ohm's Law and the power equation.
The main formulas used in this calculator are:
\[V = I \times R\] \[P = V \times I\] \[P = I^2 \times R\] \[P = \frac{V^2}{R}\]Where:
The Ohm's Law Triangle is a visual representation of the relationship between voltage, current, and resistance:
This triangle helps in remembering the relationships between voltage (V), current (I), and resistance (R). To find one value, cover it with your finger and read the equation formed by the other two.
