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
