## About Power Calculator (Formula)

The Power Calculator is a tool used to calculate the total power in an electrical circuit. It is based on the formula:

**Pt = I^2 * (R1 + R2 + R3)**

where:

- Pt represents the total power
- I is the current in Amperes (A)
- R1, R2, and R3 are the resistances in Ohms (Ω)

By squaring the current and multiplying it by the sum of the resistances, the formula determines the total power consumed in the circuit. This calculation helps in understanding the power requirements and distribution within the circuit.

Using the HTML code provided, you can input the values for current and resistances to calculate the total power. The result will be displayed on the webpage. This calculator aids in electrical engineering, circuit design, and analysis to ensure proper power management and efficiency.
