1. Electric Charge and Force: Definition, Repulsion & Attraction
Have you ever wondered what electricity is and where it comes from? Have you ever been zapped by static electricity and wondered how it got there? We'll answer all of these questions in this lesson on electric charge and force!
2. Electric Force Fields and the Significance of Arrow Direction & Spacing
Did you know that force fields don't just exist in science fiction movies? In this lesson, we'll explore the electric force fields that surround charged particles and how we can draw diagrams that represent them.
3. Coulomb's Law: Variables Affecting the Force Between Two Charged Particles
In the 18th century, Charles Coulomb uncovered the secrets of electrostatic force between charged particles. The results of his experiments led to what is now known as Coulomb's Law, which tells us how force, charge, and distance are all related.
4. Strength of an Electric Field & Coulomb's Law
After watching this lesson, you will be able to explain what an electric field is, distinguish between scalar and vector fields and use two electric field equations to solve problems. A short quiz will follow.
5. Electric Potential: Charge Collections and Volt Unit
In this lesson, we'll find out that electric charges can be rather lazy until something motivates them to get work done. Find out what gives electric charges the potential to do work and how we measure that potential with something called voltage.
6. Finding the Electric Potential Difference Between Two Points
After watching this video, you will be able to explain what electric potential difference is and calculate the electric potential difference between two points in a uniform electric field. A short quiz will follow.
7. What is Capacitance? - Definition, Equation & Examples
Capacitors are used to store and quickly release large amounts of electrical energy. In this lesson, we will learn how capacitors are created and used and how your body can function as a capacitor.
8. Capacitance: Units & Formula
After watching this lesson, you will be able to explain what a capacitor is, define capacitance, and solve simple problems using capacitance equations. A short quiz will follow.
