and Electric Circuits
Refers to electric charges flowing in a circuit through a conductor in a controlled way.
The electrical energy provided in an electrical circuit comes from the movement of electrons. The amount of energy available from each electron is called the electric potential energy of the electron.
The joule (J) is the SI unit for measuring energy.
The light bulb in a table lamp needs about 4000 J of energy for every minute it is on.
Heating 1L of water from room temperature to near boiling requires 300 000 J of energy.
Components of an Electric Circuit
1) Energy Source: Produced in a generating station and delivered to your home or produced by an electric cell (battery).
2) Load: Any device in a circuit that converts electrical energy into another form of energy.
3) Conductor/Pathway: Conducting wires connect the energy source to the load providing a controlled pathway for the electrons to flow through.
4) Switch: A break in the circuit that can be opened or closed to control the movement of electrons.
