Electricity and Atoms
PHYS 101 · Module 5
This module connects electric charge, circuits, and atomic structure. Students learn how charges interact, how simple circuits work, and how atoms and the periodic table organize matter.
Lessons in this module
Static electricity
Static electricity involves electric charges at rest or built up on surfaces. This lesson explains charge, attraction, repulsion, charging by friction, and electric fields.
Simple circuits
A circuit is a complete path for electric current. This lesson introduces voltage, current, resistance, batteries, bulbs, switches, and series and parallel circuits.
Atomic structure
Atoms are the building blocks of ordinary matter. This lesson introduces protons, neutrons, electrons, nuclei, isotopes, ions, and atomic models.
The periodic table
The periodic table organizes elements by atomic number and repeating chemical properties. This lesson explains groups, periods, metals, nonmetals, and why the table has patterns.
