Key Topics to Revise
1
Electric Charge and Its Properties
- Charge is a fundamental property of matter that causes electromagnetic interactions
- Two types of charges: positive (proton) and negative (electron)
- Like charges repel, unlike charges attract - repulsion is the sure test of electrification
2
Coulomb's Law and Electric Force
- Force between two point charges is directly proportional to product of charges and inversely proportional to square of distance
- Force acts along the line joining the two charges
- In SI units: F = kQ₁Q₂/r² where k = 9 × 10⁹ N⋅m²/C²
3
Electric Field and Electric Field Intensity
- Electric field is force per unit positive test charge: E⃗ = F⃗/q₀
- Field exists around every charge, independent of test charge
- Direction: away from positive charge, toward negative charge
4
Electric Potential and Potential Difference
- Potential is work done per unit charge in bringing charge from infinity: V = W/q₀
- Potential is scalar quantity, follows algebraic addition
- For point charge: V = kQ/r
