The section includes detailed explanations of basic circuit components:

  • Cells and batteries
  • Lamps and LEDs
  • Variable resistors
  • Switches (open and closed)
  • Diodes
  • Thermistors

Vocabulary: Current is defined as the flow of electrons through a circuit, measured in amperes (A).

Example: An ammeter measures current while a voltmeter measures potential difference in circuits.

Thermistors and Circuit Configurations

This section explores temperature-sensitive components and different circuit arrangements.

Definition: A thermistor is a temperature-dependent resistor used in various applications including central heating and street lights.

Highlight: Light Dependent Resistors (LDRs) change their resistance based on the amount of light they receive.

The section explains two main circuit configurations:

  • Series circuits: Where current remains constant throughout
  • Parallel circuits: Where current splits across different branches

Example: In series circuits, the total resistance is calculated by adding individual resistances (R₁ + R₂), while in parallel circuits, it follows the formula 1/R₁ + 1/R₂.

Energy Types and Conservation

This section provides a comprehensive overview of energy types and the fundamental principle of energy conservation. The content explores various forms of energy and their practical applications in everyday scenarios.

Definition: The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Vocabulary: Gravitational potential energy is the energy possessed by an object due to its position in a gravitational field.

The section covers multiple energy forms including:

  • Kinetic energy
  • Sound energy
  • Light energy
  • Nuclear energy
  • Chemical energy
  • Thermal energy

Highlight: Energy efficiency in homes is achieved through various insulation methods including cavity insulation, double glazing, loft insulation, carpets, and curtains.

Example: Renewable energy sources include solar, wind, water (hydroelectric), geothermal, tidal, and wave power, while finite sources include fossil fuels and nuclear energy.
