What is another term for the relationship between power, voltage, and current?

• A. Voltage Law
• B. Power Equation
• C. Watt's Law
• D. Electrical Principles

Answer: (C)

The term that describes the relationship between power, voltage, and current is known as Watt's Law. This law establishes a mathematical relationship where power (measured in watts) is equal to the product of current (in amperes) and voltage (in volts). This relationship can be expressed using the formula P = VI, where P represents power, V is voltage, and I is current. Understanding Watt's Law is crucial for professionals in building maintenance, as it aids in calculating the suitable electrical load, ensuring that electrical systems operate safely and efficiently. This principle is foundational in electrical engineering and helps in troubleshooting and optimizing electrical systems in buildings. The other terms provided do not specifically define this relationship. For instance, while the Power Equation may intuitively seem relevant, it does not have the precise standing or recognition like Watt's Law does in the context of electrical relationships. Similarly, the term Voltage Law generally refers to principles regarding voltage in circuit analysis, and Electrical Principles is a broad term that encompasses various concepts, not just the relationship in question.
