Key Topics to Revise

1

1. Electric Current and Electric Circuit

  • Electric current is the rate of flow of electric charge through a conductor.
  • A continuous and closed path of an electric current is called an electric circuit.
  • If the circuit is broken anywhere, current stops flowing and the bulb does not glow.
2

2. Potential Difference and Voltage

  • Potential difference is the work done to move a unit charge from one point to another.
  • It is the electric pressure that makes charges move in a circuit.
  • A battery or cell provides potential difference.
3

3. Ohm's Law and Resistance

  • Ohm's law gives the relation between current and potential difference in a conductor.
  • For a given metallic conductor at constant temperature, V is directly proportional to I.
  • This relation is written as V = IR.
4

4. Resistance, Resistivity, and Material Choice

  • Resistance of a uniform metallic conductor is directly proportional to its length and inversely proportional to its area of cross-section.
  • Resistance also depends on the nature of the material.
  • The resistivity formula is R = ρ l/A.
