About the lecture
In this mini-lecture we explore circuits, which are closed loops of flowing current with a source of potential energy, often from a battery, that causes the charges to flow. As we move throughout this mini-lecture, we consider: (i) circuit diagrams; (ii) resistance (R), to the flow of charge as given in Ohm’s Law, I = V/R, where I is the current and V is the voltage of the battery; (iii) examples using Ohm’s Law; and (iv) the symbols for a battery, resistor, lamp, and switch used in circuit diagrams.
