Static Electricity

In this lesson you will learn that:

  • Static electricity is a build-up of charge in an object.
  • The build-up pf charge is caused by insulating materials rub against each other.
  • The motion of these charges causes small shocks, lightening and sparks.
  • These charges can be detected. 
  • Certain materials can be classified as insulators, and others as conductors.
  • Capacitors are small devices in circuits which can store charge.
  • Lightning rods are used to allow charges from strikes to travel safely and dissipate in the Earth

Voltage in an electric circuit

When a circuit is connected and complete, charge can move through the circuit. Charge will not move unless there is a reason, a force to drive it around the circuit. Think of it as though charge is at rest and some- thing has to push it along. This means that work needs to be done to make charge move. A force acts on the charges, doing work, to make them move. The force is provided by the battery in the circuit.
