Praxis 5005 Practice Question
Which of the following are necessary for a generator to produce electricity?
Correct Answer: A
Rationale: A: Magnets and conducting wire are essential for electricity generation, as they create a magnetic field that induces an electric current when the wire moves through it, based on electromagnetic principles.
B: Natural gas and pistons pertain more to internal combustion engines than to generators, which do not require these components for electricity production.
C: Steam and steam pipes are relevant in steam turbines but not in all generators; they are not universally necessary for electricity generation.
D: Moving water and a water turbine are specific to hydroelectric generators and are not required for all types of generators, making them an incomplete answer.
