Below is a list of the animated physics lectures created thus far, covering basic electricity, the fundamentals of AC electricity, and the fundamentals of thermodynamics (currently ongoing).
In this course, I discuss the basics of electricity, starting right from the fundamental concept of charge (L1). I then discuss basic electrostatics (L2-4), before progressing to simple DC circuits (L5-8) where we consider moving charges.
Understanding the fundamentals of electric charge and its properties.
Learn how to calculate the force between charged particles using Coulomb's Law.
Generalise electrostatic interactions using electric fields.
Understand how to calculate the energy of charged objects due to an electric field, and generalise electrical energy using the electric potential.
Exactly how batteries work to hold a constant potential difference across an electrical circuit, and generate a steady electric current.
What electric current is on the microscopic level, and how resistance determines the size of a current for a given potential difference.
How to calculate energy transfer in electrical circuits, and how to generalise it with power.
How to calculate the current and power for any DC circuit using Kirchhoff's current and voltage laws.
Building on the basics of electricity, this short series covers capacitance, energy stored in capacitors, and how they behave in basic DC circuits.
In this course, I cover the fundamentals of alternating current: what it is, why we use it, how to generate it, and the main concepts: RMS values, phasors, impedance, reactance, AC power, and resonance.
What alternating current is and why we use it.
How to generate AC electricity using basic electromagnetism.
What RMS quantities are and why they are important.
Representing AC voltages and currents as rotating vectors, and why it makes circuit maths easier.
How resistance and reactance combine in AC circuits, with a visual explanation.
Power factor, the power triangle, and what “real” power means in AC circuits.
Resonant frequency, bandwidth, and Q factor, visualised.
In this course, I cover the fundamentals of thermodynamics. Currently a work in progress.
Series Introduction. What thermodynamics is really about-- and why it matters beyond “heat goes from hot to cold”.
Thermal equilibrium, temperature as a measurable quantity, and the zeroth law.
Heat, internal energy, and work-- how energy is conserved in thermodynamic processes.
