What does the I stand for in the equation P = I * V?

In the equation P = I * V, the "I" represents current. Current is the flow of electric charge through a conductor and is measured in amperes (or amps). This equation relates power (P), in watts, to current (I) and voltage (V), with current indicating how much electric charge is flowing at a given moment.

Understanding this relationship is crucial in electrical engineering and physics, as it helps you calculate the power consumption of devices based on the current flowing through them and the voltage across them. Recognizing current is vital for working with electrical circuits, as it affects how energy is used and transformed into work by electrical components.
