Key Topics to Revise

1

Electric Charge - Fundamental Properties

  • Electric charge is an intrinsic property of matter that causes electromagnetic interactions
  • Two types of charges exist: positive (proton carries +e) and negative (electron carries -e)
  • Like charges repel, unlike charges attract each other
2

Coulomb's Law and Electric Force

  • Coulomb's Law gives the force between two point charges separated by distance r
  • Force is directly proportional to product of charges and inversely proportional to square of distance
  • Force acts along the line joining the two charges
3

Electric Field and Field Lines

  • Electric field is the region around a charge where its influence can be felt
  • Field strength E = F/q₀, where q₀ is a small positive test charge
  • Electric field is a vector quantity with direction from positive to negative charge
4

Electric Flux and Gauss's Law

  • Electric flux measures the 'flow' of electric field through a surface
  • Flux depends on field strength, surface area, and angle between E⃗ and surface normal
  • Gauss's Law relates flux through closed surface to enclosed charge
