Have you ever walked across a nylon rug or carpet and felt a slight tingling sensation? This is an example of static electricity.
What Is Static Electricity?
When electrical charges build up on the surface of a material, it is called static electricity. It is called 'static' because the flow of current is absent here. Therefore static electricity stays in one place. Static electricity is usually caused when materials are rubbed together or pulled apart. The result is that objects may be attracted to each other or even may cause a spark to jump from one object to the other.
Static electricity is also termed as 'friction electricity'. When two objects rub against each other they generate electricity. This action is on account of friction. Therefore the electricity produced is known as friction electricity.
Static electricity can be experienced in winter when the air is very dry. In a dry weather, the air contains a large amount of charged particles, which cannot ground easily. During summer,the air is humid. The water in the air helps electrons move off you more quickly, so you cannot build up as big a static charge.
The Lightening Effect:-:
Static electricity can also give a shock. Lightening is also a form of static electricity. When negatively charged clouds rub against each other, they get positively charged. This causes a huge spark of static electricity in the sky called as lightening...
