What is the relationship between power, voltage, and current in electrical terms?

The relationship between power, voltage, and current in electrical terms is defined by the equation where power is the product of voltage and current. When voltage (expressed in volts) is multiplied by current (expressed in amperes), the result gives power (expressed in watts). This fundamental principle reflects how electrical energy is consumed in a circuit.

In practical applications, this means that if you know the voltage supplied to a circuit and the current flowing through it, you can calculate the total power being consumed or generated at that point. This relationship is essential for understanding how electrical systems operate and is foundational in sizing electrical components and ensuring they operate within safe limits.

Understanding this equation is particularly critical for aviation maintenance, where failure to assess the correct power consumption can lead to malfunctions. Thus, recognizing that power equals voltage multiplied by current is key to grasping the basic principles of electrical systems in aviation.
