Masterclass: Electrical & Scientific Principles (Level 2)

The Copper Connection Podcast – Season 2, Episode 42.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 EpisodeHow 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 behaviourPressure, head height, flow rate, and how bends/valves reduce performanceHeat transfer: conduction, convection, radiation (and the radiator exam trap)Electricity basics for plumbers: power triangle, Ohm’s law, MCB/RCD protection, bonding✅ Calls to Action🎧 Listen & Follow The Copper Connection Podcast so you don’t miss the next revision episodes. 🛒 Visit the Shopify Store: The Copper Connection Podcast Store 📲 Follow on Social Media for extra revision clips, reminders, and trade learning support. ⭐ Leave a review on Spotify or Apple Podcasts — it helps more apprentices and students find the show.Unit 213 plumbingElectrical and scientific principles plumbingLevel 2 plumbing revisionCity and Guilds plumbing Level 2plumbing exam revision UKplumbing pressure and flow rateheat transfer plumbingthermal expansion plumbingplumbing materials propertieselectrical safety bonding plumbingpower triangle plumbingOhm’s law plumbingCity and Guilds Unit 213 revision podcastLevel 2 plumbing exam help UKplumbing apprenticeship revision supportconstruction apprenticeship study tipshow to calculate thermal expansion in plumbingcoefficient of linear expansion plastic vs copperhow to calculate heat energy in water cylinderspecific heat capacity of water plumbinghead height and pressure explained for plumbinghow to convert litres per minute to litres per secondMCB vs RCD explained for plumbersequipotential bonding explained UK plumbingtemporary continuity bonding when cutting pipeworkconduction convection radiation radiator questionplumbing science explained simply for students#Plumbing #PlumbingApprentice #PlumbingStudents #CityAndGuilds #Level2Plumbing #TradeEducation #ConstructionApprenticeship #ApprenticeshipsUK #VocationalLearning #ExamRevision #PlumbingRevision #HeatingEngineering #TechnicalTraining #CollegeLifeUK #SkillsForLife #OnSiteLearning #UKConstruction #PodcastsUK #EducationPodcast #TradeCareersThe Copper Connection Podcast is a practical, student-first podcast built for UK plumbing learners, apprentices, and trade professionals who want clear explanations that actually relate to site work.
