Y11 Physics - Electricity - Coggle Diagram

- - - - Electrons can move from one atom to another.
        Current electricity is concerned with the movement of electric charge in conductor.
  - - - This is because the material now has more protons.
    - - This is because there are now more electrons than protons.
- - - - The higher the potential difference, the more energy the electrons have, the faster they are moving and therefore the higher the current. In other words, potential difference is proportional to current.
        If the component has a higher resistance, more energy is needed to make the same amount of current pass through. In other words, potential difference is proportional to resistance.
