Everything in the universe is made of charged particles. Learn what electric charge is, the three rules that govern it, and how Coulomb’s Law calculates the electrostatic force between any two charges with a simple formula.
Learn what electric fields and field lines are, how they work, and why they are one of the most important ideas in all of physics. Simple explanations with clear examples.
Voltage is what drives current through every circuit you have ever used. Learn what electric potential is, how it differs from voltage, what equipotential surfaces are, and how potential and electric fields are mathematically connected.
Ohm’s Law is the single most useful equation in all of circuit analysis. Learn what electric current and resistance are, how V=IR connects them, what ohmic and non-ohmic components are, and how electrical power is calculated.
Series and Parallel Circuits: How to Analyze Any Circuit in Physics Two Ways to Connect Components Every electrical circuit you will ever encounter, from the simplest flashlight to the most complex computer motherboard, is built from combinations of just two fundamental connection types: series and parallel. Everything else in circuit analysis, no matter how complicated…
