The LM317T is an adjustable voltage regulator which is capable of supplying different DC voltage outputs.
The Current Transformer (CT) is a type of transformer that is used to measure alternating current (AC). It produces a current secondary which is proportional to the current in its primary.
The video and manual provide instructions for creating a very simple circuit.

Hi, Can i use this circuit for testing any mobile without battery? and what if the mobile had short what will happened with this circuit?

Hello, this circuit functions like other power supplies. it's just not there for the current settings. to simply test a mobile can be used. but for mobile repairs, recommend to using the MBR Power Supply
