Electrostatics - Physics (Senior Secondary)
Electricity stays still before it flows, and this course explains exactly how that happens. You will learn about electric charges, how they attract or repel each other, and the invisible fields they create in the space around them. The lessons cover Coulomb's law, electric field intensity, and the way potential energy builds up between charges. You will also study capacitors, learning how they store electrical energy and why their arrangement in circuits matters for electronic devices.
This knowledge is why your phone screen reacts to your finger and why lightning strikes during a rainstorm. Understanding electrostatics is a requirement for anyone wanting to work in electrical engineering, telecommunications, or renewable energy. You can apply these principles to fix simple electronic gadgets, understand how industrial spray painting works, or ensure safety when handling flammable materials where static sparks could cause explosions. It provides the foundation for grasping how modern touchscreens and memory chips function.
By the end of this course, you will calculate the force between multiple charges and determine the strength of electric fields at specific points. You will define electric potential and solve problems involving work done in moving charges. You will also master the formulas for capacitance, including how to find the total capacity when capacitors are connected in series or parallel. This course ensures you can explain how dielectric materials affect energy storage and describe the distribution of charges on various conductor shapes.
This course is for Senior Secondary students preparing for WAEC, NECO, or JAMB exams. It simplifies difficult physics concepts into clear, manageable parts for those aiming for top grades. University undergraduates in their first year will find it a useful refresher for engineering physics. Even if you are not a science student, the course helps you understand natural phenomena like static shocks from clothes or the basic physics behind the battery-operated tools you use daily.
