Answer 1

Answer:

Which of following is not an essential element of a DC power supply? Rectifier. Voltage regulator. Filter.

Answer 2

a) In a DC power supply, the Rectifier is not a necessary component.

Provision of DC power

• A DC power supply, sometimes known as a bench power supply, is a power source that provides a device with direct current (DC) voltage. An AC, DC, battery, ultralow voltage input can be used to regulate a DC power supply subsystem.

An important part of a dc power supply.

• A transformer, a rectifier, a filter, and a regulator are the four main components of a basic power supply. A constant dc voltage is provided across the load by the dc power supply's output.
• A dc power supply does not require a rectifier.
