Power Consumption

Introduction to Power Consumption Calculator

This calculator determines the power consumed in a circuit based on the current flowing through it and the resistance of the circuit. Here, P represents the power consumed (in watts), I is the current (in amperes), and R is the resistance (in ohms). This relation is a direct consequence of Ohm's law, where power is defined as the product of the square of the current and the resistance of the circuit.

Parameter usage:

• current= current flowing through the circuit
• resistance= resistance of the circuit

Example valid values:

• current= 2 A
• resistance= 5 Ω

Output:

• power= power consumed in the circuit

Data validation

Both current and resistance must be greater than zero, ensuring practical, positive values for calculations.

Summary

This calculator is used for calculating the power consumption in electrical circuits, emphasizing the dependence on current and resistance. It is vital for electrical engineering and physics applications.
