Q:

What are the types of electricity?

A:

Quick Answer

The two types of electricity are static and current. Static electricity is the buildup of an imbalanced electrical charge on the surface of objects that causes objects to be attracted to each other. Current electricity is the flow of electrons through a conductor.

Full Answer

Static electricity is discharged when two opposite, imbalanced charges find a path to connect both groups and equalize the charges. This equalizing of charges can produce a spark or shock that can be felt, seen and/or heard.

There are two kinds of current electricity: alternating (AC) and direct (DC). Current electricity can cause the heating of a conductor, such as the coil on an electric stove.

  • Q:

    What causes static electricity?

    A:

    Static electricity is caused when objects or particles make contact and either gain or lose electrons due to friction, and the charged object discharges into a nearby object. Rubbing objects together increases the contact area. Examples of static electricity include touching a doorknob in cold weather and receiving a shock.

  • Q:

    What are examples of static electricity?

    A:

    Walking across a carpeted floor and getting a shock when touching a door knob or other metal object is an example of static electricity. Clothes stuck to one another after being in the dryer is another example of static electricity.

  • Q:

    Why is static electricity worse in the winter?

    A:

    In the winter, static electricity is worse due to a lack of air humidity, leading to a charge imbalance. In dry materials such as carpets, hair and nylon, there is a buildup of electrons that creates this charge imbalance, causing static electric to be more intense in winter's drier air. Basically, dry air is a poor conductor of electricity, while humid air is a better conductor that permits any excess electric charge to dissipate into the air.

  • Q:

    How does static electricity work?

    A:

    According to the Library of Congress, static electricity occurs when the surface charge of an object changes. If someone rubs certain types of materials together, electrons can jump from one to the other, changing the effective charge of both items. Positively charged items attract negatively charged items, while items with the same charge repel. Bringing two objects together with significantly different charges can result in a vivid spark.
