Question

Q.57. Electric transformers are used to :
A) Filter current
B) Regulate current
C Serve as fuse
D) Change voltage​

Answer 1

Answer:

Transformers are most commonly used for increasing low AC voltages at high current (a step-up transformer) or decreasing high AC voltages at low current (a step-down transformer) in electric power applications, and for coupling the stages of signal processing circuits.

Answer 2

Answer:

B) Regulate current.

Explanation:

Transformers are most commonly used for increasing low AC voltages at high current (a step-up transformer) or decreasing high AC voltages at low current (a step-down transformer) in electric power applications, and for coupling the stages of signal processing circuits.
