Praxis 5005 Practice Test Practice Question
Which of the following are necessary for a generator to produce electricity?
Correct Answer: A
Rationale: A: Magnets and conducting wires are essential for generating electricity through electromagnetic induction. When a conductor (like a wire) moves within a magnetic field, it induces an electric current.
B: Natural gas and pistons are components of a combustion engine, not directly related to electricity generation by a generator.
C: Steam and steam pipes are used in steam turbines, which convert thermal energy to mechanical energy, but they are not fundamental to all generators.
D: Moving water and a water wheel can generate electricity in hydroelectric systems, but they are not universal requirements for all types of generators.
