Q

how does a conductor work?

A
  • the conductor is made from a material that can easily transfer electricity
  • the Electrons move towards the Protons
  • most types of metals are good conductors
    - copper is used commonly

Q

What is an electric current?

A
  • it is the flow of electrons around an electric circuit
  • it needs a force to make it flow
  • the force or electric pressure is measured in volts

Q

How does an electric circuit work?

  • closed circuits
  • open circuits
A
  • The flow of electricity travels from the negative terminal on a battery to the positive terminal.
  • the battery is the power source that stores electricity
  • after the electricity flows through the light bulb it flows back to the positive terminal on the battery
  • the thin wire inside a light bulb is called the filament
  • and can glow when electricity passes through the bulb
  • the electricity will flow until the battery loses charge or the switch is opened.

Q

what are insulators?

A
  • it is the opposite of a conductor (doesn’t carry any electricity
  • they protect us (and Loki)
  • examples are rubber, plastic, glass, ceramics
17
Q

what are batteries?

A
  • stored electrical energy that can power a circuit
  • they use chemicals that react to make electricity
  • have a negative and positive end
  • when placed in a circuit the chemicals produce electricity (negatives flowing to positives).
18
Q

what is static electricity

A

-Electrons building on a surface

19
Q

oil, natural gases and coal energy

A

-they get burned down and it expands in a confined space creating pressure that can move a mechanical machine that creates kinetic energy.

20
Q

solar energy

A

-it has different layers that harness the solar energy from the sun which excites the electrons in the layers and creates electricity

21
Q

wind

A

-the wind powers the turbines and creates kinetic energy
