We introduce electricity with overviews of current and static electricity. We discuss electricity's place among the fundamental forces of the universe and discuss how it influences our daily lives.
We explain Coulomb's law both qualitatively as well as mathematically. We examine this law even further by doing an example problem where we solve for the electric force and field strengths. The properties of an electric field are also discussed.
We differentiate between the concepts of electric potential energy and electric potential by exploring electric potential energy qualitatively, looking at a charge between two parallel plates, and solving for electric potential in an example problem.
Current electricity is defined as we explore the relationship between voltage, current, and resistance. Ohm's law is introduced as well as the equation relating electric force and electric field.
We learn about the properties of series circuits. We examine how to find the total voltage, current, and resistance of a series circuit and learn how to find these things across individual resistors within the circuit.
We define the properties of parallel and complex circuits. We examine how to find the total voltage, current, and resistance of parallel and complex circuits. We also use a V.I.R. chart to find these things across individual resistors within a circuit.
We investigate the concept of electrical power by examining our own energy usage with an energy audit. Multiple electric power equations are derived, exploring the relationship between electric power and Ohm's law.
