Diesel generators are basically diesel engines that work with an electric generator such as an alternator to create energy that we sorely need. While most engines are designed to run on fuel oil such as diesel, some models utilise other kinds of liquid fuel and even natural gas.
Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well-known effects, such as lightning,static electricity, electromagnetic induction and electrical current. In addition, electricity permits the creation and reception of electromagnetic radiation such as radio waves.
In electricity, charges produce electromagnetic fields which act on other charges. Electricity occurs due to several types of physics:
