Check out these resources and educational videos for high school students to help introduce some key concepts in Electric Power Engineering.

HOW TO APPLY

Electromagnetic induction: Induced voltage in a coil of wire

Dr Martin Allen explains electromagnetic induction, Michael Faraday's second major discovery, using a coil of wire and a big voltmeter.

Electromagnetic induction: induced voltage in a single wire

Using a wire, a magnet and a voltmeter, Dr Martin Allen demonstrates how induced voltage can be created and increased.

Magnetic force on moving charged particles

Dr Martin Allen uses a vacuum tube and a bar magnet to show how moving charged particles can be deflected by a magnetic field.

The motor effect

Dr Martin Allen explains the 'magnetic force on a current carrying wire' using a modern version of Michael Faraday's first electric motor.

Electric generators and electromagnetism

Electrical Engineer Kelsey Keenan shows us what an electric power generator looks like and gives us a tour of hydro power stations that use electromagnets to generate electricity.

Electric vehicles and DC electricity

Electrical Engineer Pierce Hennessey shows us how direct current electricity from energy stored in batteries is converted to mechanical power to drive fast electric vehicles.

Capacitors part 1

Dr Martin Allen and Yanosh Irani explain how capacitors work and use them to blow up some fruit and veggies!

Capacitors part 2

Dr Martin Allen and Yanosh Irani explain how to connect capacitors in series and parallel, and show how capacitors can be used to make lightning.

Conductors and insulators

Dr Martin Allen and Yanosh Irani explain the difference between conductors and insulators, move objects without touching them, and breakdown air.

Electric charge

Dr Martin Allen demonstrates the forces between like and unlike charges and show how they 'act at a distance'.

Electromagnetic induction

Dr Martin Allen and Yanosh Irani use liquid nitrogen to levitate a magnet above a superconductor and use electromagnetic induction to melt a fork!

How hydro stations work

This video from Meridian shows how electricity is generated at a hydro power station.

How a hydro generator works

This video from Transpower looks inside a hydro generator, examines its componenents and shows how water drives the turbine to generate electricity.

How a transformer works

This video from Transpower looks inside a transformer to illustrate its key components and shows how these work together to inducts and transform electricity.

How wind energy is made

This video from Mercury shows how wind farms transform the energy from wind into electricity.

How geothermal energy is made

This video from Mercury shows how heat from the depths of the earth is used to generate electricity.

How solar panels make electricity

This video from Mercury shows how solar panels take energy from the sun's rays and turn it in to electricity for your house.

Grid-scale battery

This video from Mercury shows how battery storage could work in New Zealand's wholesale electricity market.

What if... you had solar power on your home?

This presentation (October 2015) introduces solar PV technology, examines the worldwide solar PV market, and solar PV in New Zealand. The second part covers the experience of installing solar PV on schools in Tonga, as part of an international aid programme.

What if... we all drove electric vehicles?

Electric vehicles could significantly reduce greenhouse gas emissions, provided the electricity required to power them is from renewable generation. The presentation (May 2015) provides an overview of the impact of EV and highlights the future need for skills and training in New Zealand.

Solar Panels for Tonga Project

Hear about Vladimir's experience with his final year project for Electrical Engineering at UC, installing solar panels on schools in Tonga.
