A (-) negative charge is a type of electrical charge that has the opposite polarity to a (+) positive charge. This means that negative charges are attracted to positive ones, and vice versa. Negative charge is an essential component in many scientific processes and plays a vital role in electricity generation, transmission, storage and usage.
The most common form of negative charge occurs when electrons move from one atom or molecule to another; this movement causes the atoms or molecules receiving electrons to become negatively charged as they gain extra electron particles. The process of transferring electrons between two objects can be achieved through contact with conductive materials such as metals which allow for easy transferral due their high level of free-flowing electrons. Electric fields also play an important role in creating negative electric potentials by pushing away positively charged particles while drawing negatively charged ones towards them – this effect can be seen if you place two magnets close together where like poles will repel each other while unlike poles attract one another due their opposing polarities (positive/negative).
In addition to its importance within scientific research, understanding how different forms of energy interact with each other helps us better understand our environment on a larger scale – it enables us create technologies like solar cells which convert light into electricity via the photovoltaic effect (wherein photons knock off some loose valence electron from silicon atoms causing them become electrically unbalanced) thus allowing us generate clean renewable power sources without releasing harmful pollutants into our atmosphere!
So whether we’re talking about small scale experiments involving static electricity or large scale projects involving nuclear fusion reactors – understanding how different forms energy interact with each other is essential for furthering human progress & development!
