Key Topics to Revise

1

1. Electric Current and Charge Flow

  • Lightning is an electric discharge between two clouds or between a cloud and Earth.
  • In an open circuit, random electron motion causes no net charge flow through a cross section.
  • Electric current is the amount of charge crossing any cross section of a conductor in one second.
2

2. Potential Difference and emf

  • Potential difference is the work done by electric force on unit positive charge to move it from one point to another.
  • Potential difference is also called voltage.
  • The SI unit of potential difference is volt.
3

3. Ohm’s Law, Resistance, and Resistivity

  • The potential difference between the ends of a conductor is directly proportional to the current passing through it at constant temperature.
  • George Simon Ohm established this law.
  • For ohmic materials, the V-I graph is a straight line through the origin.
4

4. Measuring Current and Voltage

  • An ammeter measures electric current.
  • An ammeter is always connected in series.
  • A voltmeter measures potential difference or emf.
