Coulomb’s Law and Voltage Voltage represents the amount of work required to move charge between two points; the amount of charge that is moving between the two points per unit time is called current. • Batteries: Electricity is produced by chemical reaction within the battery.

Electric Current For an electric current of 1 ampere, 1 coulomb of electric charge (which consists of about 6.242 × 10 18 electrons) drifts every second through any plane through which the conductor passes. Electric current is an electric charge flow, it flows from higher electric potential for lower electric potential Time (s) Direct Current and Alternating Current Residental Power distribution

    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.
