Get to grips with electric circuits in this fun and interactive tutorial.
How to make a simple electric motor at home.
In a conductor, electric current can flow freely, in an insulator it can not.
Practical projects for building many types of electric motors. Great for school projects science clubs.
The electric power in watts represents the rate at which energy is converted from the electrical energy of the moving charges to some other form
Electric motors involve rotating coils of wire which are driven by the magnetic force exerted by a magnetic field on an electric current. They transform electrical energy into mechanical energy.
A series of definitions relating to electric fields.
A basic but clear explanation of electric charge.
Both the electric field and magnetic field can be defined from the Lorentz force law. The electric force is straightforward, being in the direction of the electric field if the charge q is positive, ...
The electric current in amperes which flows into any junction in an electric circuit is equal to the current which flows out. This can be seen to be just a statement of conservation of charge.
