Question

why transformer used for set up?​

Answer 1

Answer:

ransformers are used for increasing alternating voltages at low current (Step Up Transformer) or decreasing the alternating voltages at high current (Step Down Transformer) in electric power applications, and for coupling the stages of signal processing circuits.

Answer 2

Explanation:

transformers are used for increasing alternating voltages at low current or decreasing the alternating voltages at high current in electric power application and for coupling the stages of signal processing circuits
