THEORY:

 In most of our electronic products or projects we need a power supply for converting mains AC voltage to a regulated DC voltage. For making a power supply designing of each and every component is essential. Here is the regulated DC voltage circuit which contains a bridge rectifier and a regulated IC 7805. Voltage regulator : As we require a 5V we need LM7805 Voltage Regulator IC. It has the specifications of Input voltage range 7V- 35V, Current rating Ic = 1A and Output voltage range VMax=5.2V ,VMin=4.8V.

PROCEDURE

• Set up the circuits on bread board.
• Observe the transformer secondary voltage (Vac).
• Note the output voltage of rectifier circuit (Vdc).
• Note the output voltage of regulator circuit (Vdc).
