Electric generator is a device or machines that covert the mechanical energy into electrical energy as the output. It is very important to understand that a generator does not actually creates electrical energy; instead it uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit.
An electric conductor such as copper wire moving through a magnetic field, electric current will flow, through the conductor. The moving wire’s mechanical energy is converted into electrical energy, when a magnet is moved in a coil of wire, electric current is generated.
A generator is basically created by a mechanical force that turns a conductive wire or bar within a magnetic field. The force used to spin the conductive object can be provided by many sources, such as moving water, steam, wind, gas engine or even hand-cranked levers.
Five things to know about global warming:
1. Economic consequences- most of the effects of anthropogenic global warming won’t be goof. And these effects spell one thing for the countries off the world: economic consequences. Hurricanes cause billions of dollars in damage, diseases cost money to treat and control and conflicts exacerbate all of these.
2. More floods- flooding represent one of the most dangerous hazards to human settlements and is one of the most potentially momentous impacts of global warming. As the climate changes, a warming of the seas creates ‘thermal expansion’.
3. As the planet continues to warm, dry areas of land that are already susceptible to wildfires are likely to be ravaged by even more frequent and destructive episodes.
4. With ocean temperatures being a key factor for hurricanes formation, the consequences of global warming will inevitably include the increased generation of storms and hurricanes with greater power and frequently.
5. It exacerbates pre-existing health conditions that affects the respiratory system such as emphysema, bronchitis and asthma, and in general impedes the immune system’s ability to fight against infection and disease. A hotter climate tends to lead directly to an increase in the levels of ozone, with smog-related deaths predicted or rise by “about 4.5 percent from the 1990s to the 2050s”.
