BEC BASIC ELECTRICAL CONCEPTS The following terms (in bold face type ) are the most commonly used in circuit analysis, and should be memorized. ELECTRIC CHARGE Positive charge is carried by protons. Negative charge is carried by electrons. Coulomb (C) --- unit of charge The combined charge of 6.241 X 10 18 electrons equals 1 C. ELECTRIC CURRENT ( I ) [analogy = ] 1 From Floyd Electronics Fundamentals

BEC (by convention) Ampere (A) --- Unit of electric current Ampere = coulombs/second Direct Current (DC) flows only in one direction and usually refers to a constant current. Examples: Alternating Current (AC) changes in direction of flow and usually refers to a current that varies sinusoidally with time – however, there are other waveforms. Examples: Current Source - A circuit element that provides a specified current. ( ) [ Analogy = ] 2 Current (i) Time (t) Flow of Electrons Flow of Current + _ Current (i) Time (t)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
