A charging circuit that will deliver constant DC current will be designed. The input of the circuit is 220V / 50Hz AC and its output It will be 5V / 2A DC. The circuit will consist of 3 parts: AC transformer will reduce the voltage on the input ii. AC rectifier circuit will convert low AC voltage to DC iii. Current source, this part will keep the current at the output constant. You determine the transformer drop rate in the first part. Its output is low voltage AC as the source and design the second and third parts accordingly.

Semiconductor components such as diodes and transistors are easily damaged by the high temperatures of soldering, so care must be taken to protect these components during the soldering process. One way to do this is to use a heat sink to draw heat away from the component without cooling the connection point too much. Heat sinks made out of sheet metal may be temporarily clipped to the component leads, one at a time, to prevent the solder's high temperature from thermally conducting all the way to the component body:   In the absence of a formal heat sink, can you think of any ways to fashion your own ïmpromptu" heat sinks out of commonly available tools and/or objects?
