What is a transformer used for?
A transformer is a device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing (stepping up) or reducing (stepping down) the voltage.
Which of the following does the transformer do?
A transformer is used in the case of changing voltage. To satisfy the given condition, the current must be changed while also changing the voltage. Therefore, a transformer can accomplish changing both the current and the voltage. The correct option is D) Changing both current and voltage.
What is a transformer and where might it be used?
Transformers help improve safety and efficiency of power systems by raising and lowering voltage levels as and when needed. They are used in a wide range of residential and industrial applications, primarily and perhaps most importantly in the distribution and regulation of power across long distances.
What does a transformer do quizlet?
The basic transformer is an electrical device that transfers alternating current energy from one circuit to another circuit by magnetic coupling of the primary and secondary windings of the transformer. … The higher the K of the transformer, the higher is the transfer of the energy.
