Summary of the Circuit
This circuit appears to be a power supply unit that takes an AC input and converts it to a regulated DC output. The AC supply is first transformed to a lower voltage level, then rectified by a bridge rectifier. The resulting pulsating DC is smoothed by an electrolytic capacitor. Finally, a 7808 voltage regulator is used to provide a stable 8V DC output. A multimeter is included in the design for measurement purposes.
