Explore electricity fundamentals and dc circuits, from voltage, current, and resistance to electrical symbols, wiring, meters, and various circuit configurations, including capacitors and dc rc concepts.
Understand voltage as the potential difference that drives current; batteries provide energy via their positive and negative terminals. See how wiring cells in series increases total potential difference.
Explore how wiring batteries in parallel affects voltage and extends longevity, versus series configurations that deplete power faster, and why household batteries differ in longevity more than voltage.
Explore how resistance impedes current, why short circuits are dangerous, and how a resistor provides controlled resistance to shape circuits, measured in ohms.
Master ohm's law, linking voltage, current, and resistance with V = IR. Learn how voltage and resistance shape current in a circuit containing a battery and a resistor.
Examine how resistivity and wire geometry set resistance using R = ρ L / A. See how length, cross-sectional area, and material affect resistance, with temperature considerations.
Explore how meters measure current in circuits, navigate simulation pitfalls, and understand why short circuits follow the path of least resistance to challenge measurement accuracy.
Explore how energy and power flow in circuits, showing that the battery's energy equals the energy used by a bulb, with voltage, current, and resistance governing the process.
Explore how Ohm's law links current, voltage, and resistance, distinguishing ohmic (linear, constant resistance) from non-ohmic devices, with examples like motors and incandescent bulbs and temperature effects.
This lecture guides a high school regents electricity worksheet, showing how to build knowns list and apply i = Δq/Δt to find charge, current, or time, including electron charge calculations.
Explore how current, the flow of charge per time, arises from converting elementary charges to coulombs, and apply this to resistors, light bulbs, and cells to determine amperage.
Explore how resistance in wires depends on resistivity, length, and cross-sectional area, apply Ohm’s law, and analyze temperature effects on resistance through copper examples.
Master ohm's law through practice problems, deriving current from voltage and resistance using V = I R, and analyzing how changing resistance affects current in simple circuits.
Explore electrical power using Ohm's law and P = IV, plus P = V^2/R. Compare 50 W and 100 W bulbs at the same voltage to show current and resistance.
Master AP-level electricity concepts through conceptual multiple-choice questions on current, electrons, voltage, Ohm's law, and analyze resistor geometry and slope interpretations.
This course is one of several Mousseau Physics courses designed for students in high school physics, AP Physics, and introductory college physics. In this course we focus on current electricity and the basic ideas needed before more complex circuit analysis. Students will study electric current, voltage, resistance, Ohm's law, electrical energy, electric power, and the relationships between the variables used in simple electric circuits.
The videos and resources include clear lectures, demonstrations, diagrams, and worked out example problems. Students will practice using equations, interpreting units, distinguishing voltage from current, and understanding how resistance affects a circuit. The course emphasizes conceptual understanding because electricity vocabulary can be confusing when students first encounter it.
This course is a strong fit for high school physics students, AP Physics students, and introductory algebra based college physics students who want a clear foundation before moving into series circuits, parallel circuits, combination circuits, and Kirchhoff's laws. It does not require calculus. It can also work as a focused review for students who learned circuits before but never felt comfortable with the core variables.
By the end of the course, students should be more comfortable with the language of electric circuits, more confident using Ohm's law and power relationships, and better prepared to solve quantitative electricity problems in later circuit units.
Students can work straight through the course as a full unit or use individual lessons as targeted support alongside a class. The videos are built to be paused, rewound, and practiced with pencil and paper, so the course works well for homework help, test review, exam preparation, or rebuilding a topic that did not fully click the first time.
