What is the formula for calculating electrical power?

The formula for calculating electrical power is given by P = Voltage x Current. This relationship indicates that electrical power (measured in watts) is directly proportional to both the voltage (measured in volts) and the current (measured in amperes) flowing in a circuit.

In more technical terms, power represents the rate at which electrical energy is converted into another form of energy, such as heat, light, or mechanical energy. By multiplying voltage and current, you effectively determine this energy transfer rate within the electrical system.

Understanding this formula is fundamental in electrical engineering and related fields, as it allows professionals to calculate how much power is consumed or produced by electrical devices, which is crucial for system design, efficiency assessment, and safety analysis.
