The Copper Connection Podcast – Season 2, Episode 42. Masterclass: Electrical & Scientific Principles Exam Prep for your Level 2 Plumbing

Level 2 plumbing students and construction apprentices — this Unit 213 revision episode makes the “science bit” finally click.

Master pressure, heat transfer, water properties, materials, and electrical safety in a clear, exam-focused recap.

Welcome back to The Copper Connection Podcast with Chris Bailey, Plumbing Tutor and Industry Mentor. If Unit 213 (Electrical and Scientific Principles) feels overwhelming, you’re not alone — but it’s also one of the easiest units to score well in once you understand how it links to real plumbing and heating systems.

In this masterclass-style recap, Chris walks you through the full journey of Unit 213 in a way that’s practical, simple, and designed for exam success. You’ll learn what the examiner is really looking for, the definitions you must be able to say confidently, and the calculations that come up again and again in City & Guilds Level 2 plumbing papers.

This episode is built for revision on the move — whether you’re on the bus to college, in the van, or between jobs in the workshop. By the end, you’ll be clearer on the key facts, more confident with the maths, and far less likely to fall into the common traps that cost students marks.

📌 What You’ll Learn in This Episode

• How material properties affect pipework choice (ductility, malleability, conductivity)
• Thermal expansion and the coefficient of linear expansion (what to calculate and why)
• Water, liquids, and gases: density, capillary action, and safety-relevant gas behaviour
• Pressure, head height, flow rate, and how bends/valves reduce performance
• Heat transfer: conduction, convection, radiation (and the radiator exam trap)
• Electricity basics for plumbers: power triangle, Ohm’s law, MCB/RCD protection, bonding
