Practical Example

Imagine you are designing a simple circuit with a current of 3 A and a resistance of 12 Ω.

Input 3 into the Current field.
Input 12 into the Resistance field.
Click Calculate Voltage.

The calculator will display: V=3×12=36.00 VV = 3 \times 12 = 36.00 \text{ V}V=3×12=36.00 V

Now you know the voltage across your circuit is 36 volts. This allows you to select components that match this voltage safely and efficiently.
