Example Use Cases

Let’s consider a few real-world examples to see how this calculator can be useful:

Example 1: Calculating Power (Watts)

You want to know how much power your electrical device consumes. You know the voltage (120V) and the current (3A).

  1. Choose Power from the dropdown.
  2. Enter Voltage = 120V and Current = 3A.
  3. Click Calculate.
    The result will show that the power consumed by the device is 360W (P = V × I).

Example 2: Finding Voltage (Volts)

You’re working with a motor and know the current is 2A and the resistance is 6Ω.

  1. Choose Voltage from the dropdown.
  2. Enter Current = 2A and Resistance = 6Ω.
  3. Click Calculate.
    The result will show the required voltage to be 12V (V = I × R).

Example 3: Determining Resistance (Ohms)

You’re trying to determine the resistance of a resistor used in a circuit. You know the voltage (10V) and the current (0.5A).

  1. Choose Resistance from the dropdown.
