Basics of Electrical and Electronics course gives the introduction and working of small concepts in these two fields. Electrical and Electronics is the heart of most of the latest applications. Foundation of such things must be concrete. Hence this course will help in doing those things.
Sal shows that there will be a net torque on a loop of current in a wire. Sal shows that this net torque will cause the loop to rotate. Created by Sal Khan.
Sal finishes the explanation of how a commutator will allow a loop of wire to continue spinning in a magnetic field, thereby allowing it to work as an electric motor. Created by Sal Khan.
Play with a bar magnet and coils to learn about Faraday's law. Move a bar magnet near one or two coils to make a light bulb glow. View the magnetic field lines. A meter shows the direction and magnitude of the current. View the magnetic field lines or use a meter to show the direction and magnitude of the current. You can also play with electromagnets, generators and transformers!
Explore the interactions between a compass and bar magnet. Discover how you can use a battery and wire to make a magnet! Can you make it a stronger magnet? Can you make the magnetic field reverse?
This activity describes a simple clear demonstration of electric generators (Faraday's Law) and electric motors (Lorentz Force). This demonstration can be used as an interactive lecture demonstration.
The activity presents an interactive lecture demonstration of the operation of a transformer using a simulation.
