Question

St electric generators used direct current, so they needed to be reversed manually on a regular basis in order to

work properly Nikola Tesla saw this as an inefficient way to produce electricity. As a result, Tesla used the idea of the
rotating magnetic field, which had been developed by François Arago, to invent the induction motor, which reverses
automatically How is this an example of a scientist applying creativity to solve a problem?
O Tesla investigated a new problem that no one had considered before.
O Tesla designed a new experimental method for research.
O Tesla invented an entirely new concept to replace an inefficient design.
O Tesla used another scientist's research to help develop his own solution to a problem.

Answer 1

Tesla used another scientist’s research as inspiration. (The last one)

Step-by-step explanation:

Tesla used someone elses idea of a rotating magnetic field. This dosen't mean he plagarized another scientist work, but he needed the scientific concept to create something new.
