Electric fields are everywhere and they can play a significant part in everyday life and science.
One of the most common examples seen of the existence of electric fields and their effects can be seen when a balloon is rubbed against a sweater and the balloon becomes charged and electric field is generated.
As a result of charge and the fact that like charges repel and unlike ones attract, the balloon can stick to walls. It is the electric field associated with the charge that enables the charges to repel and attract each other.
The basics of electric fields and their impact on items like electronic components and various electrical items can be quite important, so an understanding can not only be useful from having a wider view of electrical phenomena, but also from a practical viewpoints.
