Key Topics to Revise

1

Electric Current and Circuit

  • Electric current is the flow of electric charges through a conductor
  • Electrons constitute the flow of charges in metallic wires
  • Conventional current direction is opposite to electron flow (positive to negative)
2

Electric Potential and Potential Difference

  • Potential difference is needed for current flow (like pressure for water flow)
  • Cell/battery provides potential difference through chemical energy
  • Potential difference is work done per unit charge
3

Ohm's Law

  • Current through conductor is directly proportional to potential difference
  • Temperature must remain constant for Ohm's law to apply
  • V-I graph is a straight line passing through origin
4

Factors Affecting Resistance

  • Resistance depends on length, area of cross-section, and material
  • Resistance is directly proportional to length
  • Resistance is inversely proportional to area of cross-section
