## About Electricity Calculator

The electricity calculator is a tool that can help you solve problems involving voltage, current, resistance, and power in an electrical circuit. It uses two laws of physics, Ohm's Law and Watt's Law, to calculate unknown values in a circuit.

The two formulas used by the calculator are:

1. v=ir: This is Ohm's Law, which states that the voltage (v) in a circuit is equal to the current (i) flowing through the circuit multiplied by the resistance (r) of the circuit.

2. p=iv: This is Watt's Law, which states that the power (p) in a circuit is equal to the voltage (v) multiplied by the current (i) flowing through the circuit.

To use the electricity calculator, simply enter the values you know into the appropriate fields and click the "Calculate" button. The calculator will then use the appropriate formula to solve for the unknown value in the problem.

The electricity calculator is a valuable tool for anyone studying electricity or working with electrical circuits. Try it out today and see how it can help you solve your electrical problems.
