Level 2 Electrical Installation (2365-02) – Unit 202: Resistivity | Part 1

This video forms part of the Level 2 Electrical Installation qualification (2365-02) and covers Unit 202: Resistivity. It is Part 1 of 6 within this unit and is intended for learners at the foundation stage of electrician training in the UK. This unit explains the concept of resistivity and how the physical properties of a conductor affect its resistance. Understanding resistivity is essential for cable selection, voltage drop calculations, and safe electrical design. This video covers: What resistivity is and how it differs from resistance How conductor length affects resistance The relationship between resistivity, length, and resistance The content is delivered in a structured, classroom-style format and reflects how the qualification is taught within a formal training environment. Qualification pathway context: Resistivity underpins later learning at Level 2 and Level 3, including voltage drop, cable sizing, and inspection and testing.
