Question

The group of electrical equipment or apparatus used to change characteristic of electric power known as
​

Answer 1

Answer:

Efficiency is the most important power supply characteristic affecting an electronic system's operation, but other factors, such as  output overcurrent, overtemperature, inrush current,  output overvoltage,  drift, dynamic response, line regulation, and load regulation, are also important

Answer 2

Transformer

• As we know that a transformer is a component that is used to transfer electrical energy from one electrical circuit to multiple circuits.
• The electrical energy can be transferred between separate coils without a metallic connection between the two circuits.
• And the transformers are most commonly used for increasing low AC voltages at the high current or decreasing high AC voltages at low current in electric power.
• Hence, the group of electrical equipment or apparatus used to change characteristics of electric power is known as Transformer.
