The amount of power used by each resistor can be found by using _____ law?

The correct answer is Watt's law, which relates to the power consumed by resistors in an electrical circuit. Watt's law states that the power (P) in a circuit is equal to the current (I) flowing through it squared, multiplied by the resistance (R). This can be mathematically expressed as P = I²R. This fundamental relationship allows you to calculate the power dissipated in a resistor based on the current flowing through it and its resistance.

Understanding Watt's law is crucial for tasks such as determining how much heat a resistor will generate and ensuring that components are used within their safe operating limits. This knowledge is vital in various applications, including circuit design and troubleshooting.

Other laws, like Ohm's law, are important for understanding voltage (V), current, and resistance within circuits, but they do not directly address the relationship between power and these quantities. Kirchhoff's laws focus on the conservation of charge and energy within electrical circuits, whereas Faraday's law pertains to electromagnetic induction, which does not relate directly to the power across resistors in the context of basic circuit analysis. Consequently, Watt's law is the most appropriate choice for finding the power used by each resistor.
