EXPLANATION
- a) Magnetism
- b) Optics
- c) Electrodynamics
- d) Nuclear physics
ANSWER: c) Electrodynamics
EXPLANATION:
The branch of physics that investigates the principles of electricity and electrical circuits is c) Electrodynamics. Electrodynamics is a branch of physics that studies the relationship between electric and magnetic fields and their interactions with charged particles and currents. It encompasses the principles and laws governing the behavior of electric charges, electric fields, electric currents, and magnetic fields. Electrodynamics includes topics such as electromagnetic induction, Maxwell's equations, electric circuits, and the behavior of electrical components. It forms the foundation for understanding the principles and functioning of electrical systems and devices, such as generators, motors, transformers, and electronic circuits. Magnetism, optics, and nuclear physics are separate branches of physics that investigate different aspects of the physical world.
