The digital energy meter for any device which is under the range. In older induction motor based energy meter has great disadvantage like, they work on mechanically operation, they can not show the voltage, current and power consumption by particular in load whole system also they can not show the power factor and frequency. Due to this reasons, in this project we have develop the digital energy meter which is based on microcontroller. This energy meter can solve these problems.

The present of battery charger is of great important in today’s technology advancement. Charger serves as the live wire of the backup power supply system in our day-to-day technological development. “The variable battery charger” is a device design to build up electrical energy in wet cells through the help of a transformer that takes in 220/230V and rectifier circuit which contain diodes to convert the alternating current [AC] from the transformer to direct current [DC], the output from the rectifier was being smoothen by a capacitor and then regulated by an integrated circuit (IC), the output is varied to the desire voltage by the use of variable resistor. The components as stated above were carefully arranged and soldered part by part together and coupled in a metal casing of 40*30*20cm. finally it was tested and work perfectly well. “This variable battery charger” can be used to charge automobile and portable equipment batteries with voltage ranging from 6- 36volt. To charge a battery, the charger voltage has to be greater than the terminal voltage of the battery. When a battery is connected to this charger, the dial of the ammeter will read to the near current require by the battery to start charging. The charger ammeter begins to draw until when it finally drops to zero indicating that the battery is fully charged.

This project is designed to develop High Voltage dc around 4KV from supply source of 230 V AC using capacitors and diodes in Karl Marx circuit. The design of the circuit involves voltage multiplier; whose principle is to go on doubling the voltage for each stage. The output from a 16 stage voltage multiplier can generate up to 4KV. The output from this circuit is used to separate carbon and oxygen from its molecule compound from Carbon Dioxide, which was being emitted to atmosphere through Chimney.
