Key Topics to Revise
1
Electric Charges and Their Properties
- Electric charge is a fundamental property of matter carried by protons (+e) and electrons (-e)
- Elementary charge e = 1.6 × 10⁻¹⁹ C is the smallest unit of charge
- Matter is normally electrically neutral due to equal numbers of protons and electrons
2
Coulomb's Law and Electric Force
- Coulomb's law quantifies the force between two point charges at rest
- Force is directly proportional to product of charges and inversely proportional to square of distance
- Electric force is a central force acting along the line joining the charges
3
Electric Field and Field Intensity
- Electric field exists around every charge and exerts force on other charges placed in it
- Electric field intensity is force per unit positive test charge
- Field is independent of test charge but depends on source charge and distance
4
Electric Field Lines and Properties
- Electric field lines provide visual representation of electric field
- Field lines start from positive charges and end on negative charges
- Tangent to field line gives field direction at that point
