In digital circuitry however there are only two states. Conductors present very low resistance to the flow of current whereas insulators conduct very little current even when a large potential difference is applied. Semiconductors are materials that exhibit electrical behavior somewhere between that of insulators and that of conductors.
This free electrical engineering textbook provides a series of volumes covering electricity and electronics.
These worksheets are a free and fun way to test your electrical engineering knowledge. Lessons in electric circuits. All about circuits is an international web based community of electrical engineers and designers seeking ideas education and discussions. Alternating current is when current flows in one direction for a set time then changes direction then changes back and so on in a repeating cycle.
