Voltage: a measure of the energy gained by a unit of charge as it moves through the battery - Units: volts (V) or joules per coulombs (J/C) Current: the time rate of flow of electrical charge through a conductor or circuit element - Units: amperes (A) or coulombs per second (C/s) - Electron charge = 1.6 x 10^-19 C Power = Voltage x Current (P=IV) - Units: volts x amperes (V*A) or watts (W) or joules per second (J/s) Energy: integrate power: int (t1 => t2) of p(t) dt KCL (Kirchhoff’s current law) - Node: a point at which two or more circuit elements are joined together - All points in a circuit that are connected by ideal conductors are a single node - KCL: - The net current entering a node is zero - The net current leaving a node is zero. - The sum of the currents entering a node equals the sum of the currents leaving the node - Electrical forces prevent charge from accumulating at the nodes of a circuit Series: elements are connected end to end - All currents are the same KVL (Kirchhoff’s voltage law)

### What students are saying

• 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.
