How Electricity Works.

What voltage, current and the neutral actually are, shown in 3D — from a single electron to a grid that spins at fifty hertz.

overview

Thirteen narrated 3D explainer episodes in four modules, from what an electron actually is to why the grid runs at fifty hertz. Along the way: where voltage comes from, why the energy travels in the fields around the copper, and why the neutral reads zero volts but still carries current. Each module ends in a quick check, and you finish with a spoken scenario, explaining the neutral to a homeowner as a first-year apprentice. No physics background assumed.

Narrated 3D episodes that show what's actually going on in the wire: the electron blur, the trampoline and the smoke rings, the neutral at sea level, and generators spinning in step. Start on smoko, pause, pick it up on the train.

what’s covered
01

Not a ball, a blur

3 topics
  • What an electron actually is — a spread-out blur, not a tiny marble
  • The two fields: the trampoline (electric) and the smoke rings (magnetic)
  • Magnetism rides on movement, not on the push
02

Voltage pushes, current moves

3 topics
  • Where voltage comes from — separated charge, and the four pumps that build it
  • Copper versus rubber: why only free electrons can carry current
  • The wire is a guide rail — the energy travels in the fields around the copper
03

Zero volts is not nothing

3 topics
  • The grid, and AC as a slosh fifty times a second
  • Why the neutral reads zero volts but still carries current
  • Current loops back, energy doesn't — and why active and neutral run together
04

Every shaft in step

3 topics
  • How a generator makes its own magnet
  • Fifty hertz: every generator on the grid spinning in step
  • Why the grid runs on AC, and why fifty

how it works
FormatTap-through microlearning — ~1 hr 10 min · online. Built for phones, works everywhere. Start on smoko, pause, pick it up on the train.
PracticeScenario cards drop you into real situations along the way — you make the call a worker actually faces, then get the reasoning, straight up.
ChecksQuick knowledge checks in every module. Not exam-style — the course makes sure it sticks before it moves on.
You leave withA certificate of completion from an RTO-crafted course, issued instantly and logged in the Nexa Compliance Hub — with refresher reminders.
questions
No. This is an awareness course — practical, RTO-authored online training that issues a certificate of completion. It is not a nationally recognised unit of competency.
~1 hr 10 min · online. Delivery: online, self-paced. Start, pause, and finish whenever suits.
No. It isn't a licence or a competency course, and it doesn't qualify or prepare anyone to do electrical work. That's done by licensed electricians, or by apprentices under their supervision. This course explains what's actually going on in the wire — voltage, current, the neutral — so the rules you learn on the job make sense.
No. It sticks to how electricity works: electrons and the two fields, voltage and current, conductors and insulators, AC, the neutral at zero volts, cables side by side, generators and fifty hertz. RCDs, earthing systems, three phase and power factor aren't covered (the MEN link comes up only to explain why the neutral sits at zero volts), and neither is how to do electrical work.
No. No physics background is assumed, and every technical word is explained the first time it comes up. Each idea is shown as a picture you can hold in your head — the trampoline, the smoke rings, the hill, the bike chain and sea level.
A phone or a computer with an internet connection. Every episode is narrated, so turn the sound on, or follow along with the captions. The final scenario is a spoken conversation, so find a spot where you can talk.
You play a first-year apprentice. Bev, the homeowner, wants to know why the neutral reads zero volts when it still carries current, and why a broken neutral is dangerous. You explain it out loud, in your own words, using the pictures from the course.
