The equation for Watt's Law is expressed as?

Watt's Law defines the relationship between power, voltage, and current in an electrical circuit. The correct formulation, expressed in the equation P = EI, indicates that power (P) in watts is equal to the voltage (E) in volts multiplied by the current (I) in amperes. This law is fundamental for understanding how electrical power is consumed in a circuit and is pivotal in various applications, including electrical engineering and energy management.

Knowing this, the other options do not accurately express Watt's Law or its principles. For instance, the formulas involving R (resistance) do not correctly represent the relationship of power, voltage, and current as dictated by Watt's Law. The correct reading of this law is essential for anyone working with electrical systems, ensuring accurate calculations of power consumption and circuit design.
