    What is Static Electricity?

    January 7, 2022 By Emma Vanstone Leave a Comment

    Have you ever had an electrostatic shock from a shopping trolley or escalator or noticed your hair standing on end when you rub a balloon on it? The shock is because of static ( non-moving ) electricity caused by electrons building up with no circuit to flow along.

    An object that has gained electrons has a negative charge. An object which has lost electrons has a positive charge. When a charged object is near another charged object the two will either attract or repel each other.

    Objects with a charge try to gain or lose electrons to become neutral again. Sometimes you can see a tiny flash as the electricity is discharged.

    Remember – opposite charges attract and like charges repel

    What is an atom?

    All materials are made of atoms.

    Atoms contain tiny particles called protons, neutrons and electrons (subatomic particles ). Protons and neutrons are found in the nucleus of an atom. Protons are positively charged. Negatively charged electrons orbit the nucleus. Atoms usually have an overall neutral charge.

    Why do balloons become charged with static electricity?

    Balloons and some other objects like fluffy jumpers can steal electrons from other surfaces. The extra electrons give the balloon a negative charge. This attracts other objects, such as tissue paper which jump up to the charged balloon.

    Why does a balloon charged with static electricity stick to a wall?

    When you rub a balloon on your hair electrons are transferred to to the balloon giving it a negative charge. When you place the balloon on a wall it sticks. This is because the negative charge on the balloon repels the negative charges on the wall, creating a positively charged surface to attract the negatively charged balloon. This is attraction by induction.

    Why do you get an electrostatic shock?

    You get an electrostatic shock when charge builds up on you and you touch something that is earthed or vice versa.

    For example, if you scuff your feet along a carpet and then touch another person or a metal object you’ll get a static shock as the electrons jump from you to the other object!

    How is static electricity different to electricity?

    We usually think of electricity as a current that flows.

    Static electricity is a build up of electrons without a current to flow along.

    When is static electricity dangerous?

    When static electricity builds up on an object the potential difference between the object and the earth increases. If the potential difference becomes big enough electrons can jump from the charged object to the earth creating a spark.

    • Sparks in places with flammable materials can cause an explosion.
    • Build up of static charge can interfere with radio equipment.
    • Lightning is also caused by static electricity and can cause fires when it reaches the ground.

    How can you stop static charge building up?

    To prevent too much static charge building up, objects can be earthed. This means a conductive material is used to give a route for the static charge to travel to the ground. This stops the static electricity building up.

    Uses of static electricity

    In a photocopier

    Reducing dust and smoke.

    In electrostatic sprayers.

    Easy static electricity demonstrations

    You can use static electricity to make tissue paper frogs jump up to a balloon. This is a lovely simple activity that can be turned into an investigation by using different types of paper or by rubbing the balloon for different lengths of time on a surface to charge it.

    Frugal Fun for Boys and Girls has a great jumping goop investigation.

    Learn, Play, Imagine has a fun way of creating a static electricity spark.

    Do you have any static electricity experiments to share with us?
