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

In the equation ( P = I \times V ), the letter "I" stands for current. This equation is a fundamental relationship in electronics known as Ohm's law, where ( P ) represents power measured in watts, ( I ) represents current measured in amperes, and ( V ) represents voltage measured in volts. Current is the flow of electric charge, and this equation highlights how power is calculated by multiplying the current flowing through a circuit by the voltage across that circuit.

Understanding that current is essential in determining electrical power helps in various applications, such as circuit design and troubleshooting. The equation illustrates that for a given voltage, an increase in current will result in an increase in power consumption, which is crucial for managing electrical systems effectively.
