Benefits of Static Electricity We can recognize the benefits of static electricity everyday life include: a. clotting smoke This tool serves to clean the ash particles of combustion gases in the chimney, thereby reducing air pollution. b. Painting a car In the car painting before painted, sanded the car usually first, so rubbing and will generate an electric charge. While the current electrostatic paint sprayer will spray, the droplets of aerosol paint would rub the spray nozzle and the air so that the paint will be electrically charged particle. As a result, the charge will be drawn to the car body and paint will stick to the car body. This method is very effective, efficient, and low cost. c. Photocopiers The workings of this machine is based on the concept of static electricity, and optics. inside the engine there are metal selenium (a photo conductor), that conduct electric current when exposed to light and is an electrical insulator when in darkness. d. laser printer The tool consists of a photoreceptor drum, fuser, corona wire, laser, and toner. The working principle of this device is the laser irradiation and heating process. Introduction to the benefits of static electricity is very important in life to help people simplify the job. question: 1. How is the beginning of the static electricity? 2. How do I work out of a laser printer that uses static electricity?
