BASIC ELECTRICITY 4

Electrical circuit connection

An electric circuit is a closed loop or pathway through which electric current can flow. It typically consists of components like resistors, capacitors, inductors, and various types of electronic devices, all connected by conductive wires. The circuit allows the flow of electric charge, enabling the operation of electronic devices and systems.

Types of electric circuit

There are two main types of electric circuits:

1. Series Circuit: Components are connected in a single path, and the same current flows through each component sequentially. If one component fails, the entire circuit may be affected.

2. Parallel Circuit: Components are connected in multiple paths, and each component has its own branch. The voltage across each component is the same, but the current may vary. If one component fails, others continue to function independently.

Wiring tools and materials

Common wiring tools and materials for electrical work include:

Tools:

  1. Wire stripper
  2. Pliers
  3. Screwdrivers (flathead and Phillips)
  4. Wire nuts or connectors
  5. Voltage tester
  6. Multimeter
  7. Cable or conduit cutter
  8. Fish tape (for pulling wires through conduits)
  9. Electrician's tape
  10. Circuit tester

Materials

  1. Electrical wires (various gauges and types)
  2. Circuit breakers or fuses
  3. Electrical boxes
  4. Switches and outlets
  5. Conduit (metal or plastic)
  6. Junction boxes
  7. Wiring connectors
  8. Cable ties
  9. Wire staples or clips
  10. Grounding materials (grounding wire, grounding rod, etc.)

EVALUATION: 1. What is electric circuit connection?

  1. Mention and discuss the types of electric circuit you know.
  2. Identify 10 tools and materials for wiring.

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the students positively
