Circuit analysis is the process of finding all the currents and voltages in a network of connected components. We look at the basic elements used to build circuits, and find out what happens when …

We will create our first mental models for these basic electrical quantities. We will also talk about power, which is what happens when voltage and current act together.

Between the 18th and early 19th century, before scientists could observe electrons, they believed that electrical charge flowed from positive to negative. They then learned, sometime in the 1850s or …

Review the components of a circuit and their symbols such as battery, resistor, and switch. Analyze how the power of a resistor is related to the current and electric potential difference across the resistor.

Circuit analysis, or solving a circuit, means figuring out voltages and currents in each element. Here's an overview of circuit analysis, with some context for the various tools and methods we use to analyze …
