25 Electromagnetic Induction

This page covers the EM Induction section of the course.  It is really key again you learn the definition slides I have put  here and revisit them over and over. They will eventually make sense but it takes a lot of recap to be sure.

What is regenerative braking? How do electric cars and hybrid cars regenerate power through braking? How does regenerative braking work? Regenerative braking is a fairly easy to understand concept, once ...one understands how motors work, and how generators work. Regenerative braking translates to energy savings, as it recovers kinetic energy. A motor can simply be reversed in order to generate electricity, acting as a generator to recharge a vehicle's battery pack.

This video is a bit of fun. If you take a 13A 230V primary connection on 800 turns and reduce N to just 5 turns the current increase is to ...about 2000A.

This means the nail will be extremely dangerous to touch and this would kill you. So take care!

If you use the transformer equation then the power equations you can work out the output current assuming 100% transfer.

Ploss= I*I*R. The reduction in lost energy is useful as the current is much reduced.
