Answer :
In the context of automotive electrical systems, if a Mercedes-Benz auxiliary battery experiences a malfunction, the primary physical principle involved in diagnosing the issue is Ohm's Law.
Ohm's Law is a fundamental principle in electrical engineering and physics that describes the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. It is mathematically expressed as:
[tex]V = I \times R[/tex]
The other options—Bernoulli's Principle, Newton's Third Law of Motion, and Coulomb's Law—do not directly apply to diagnosing electrical malfunctions in automotive systems:
- Bernoulli's Principle relates to fluid dynamics and pressure differences in fluids.
- Newton's Third Law of Motion involves the relationship between forces and their reactions.
- Coulomb's Law describes the force between two charged particles.
