Electric Charge and Force: Definition, Repulsion & Attraction

1. Electric Charge and Force: Definition, Repulsion & Attraction

Electricity is created by the electric charge that electrons and protons possess. Explore atoms and electric charge, ions, conservation of charge, forces between charged particles, and static electricity.

Electric Force Fields and the Significance of Arrow Direction & Spacing

2. Electric Force Fields and the Significance of Arrow Direction & Spacing

Electric force fields exist not only in science fiction movies, but also in everyday life, at the atomic level. In this lesson, dive into electric force and what exactly is significant about arrow direction and spacing in electric field diagrams.

Coulomb's Law: Variables Affecting the Force Between Two Charged Particles

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 two charged particles, including the effect of particle charge and the combined effects of charge and distance. In this lesson, dive into the definition of a coulomb as a unit of charge and the variables that affect the force between two charged particles.

Electric Potential: Charge Collections and Volt Unit

4. Electric Potential: Charge Collections and Volt Unit

Charge collections, or groups of charged particles, determine electric potential. Learn about charge collections, volt units, the effect of charge density, and how voltage is created and measured.

Insulators and Conductors: Examples, Definitions & Qualities

5. Insulators and Conductors: Examples, Definitions & Qualities

Not all atoms and materials conduct electricity the same way. Define conductivity, learn about insulators and conductors, and understand that good electrical conductors also act as good heat conductors.

Voltage Sources: Energy Conversion and Examples

6. Voltage Sources: Energy Conversion and Examples

Electrons are motivated to power circuits through voltage sources, which can be clearly seen in batteries and other everyday items. Generators can come in the form of nuclear, coal, natural gas, hydroelectric, and wind power to generate voltage. In this lesson, learn about energy conversion, voltage, voltage sources, and examples of these things in everyday life, including batteries and generators.

What is Electric Current? - Definition, Unit & Types

7. What is Electric Current? - Definition, Unit & Types

Electrical current involves the flow of charged particles, or electrons, and it is an integral part of electricity. In this lesson, we will dive into the definition of current, as well as the unit and types to understand just how electricity moves.

Electrical Resistance: Definition, Unit & Variables

8. Electrical Resistance: Definition, Unit & Variables

Electrical resistance refers to the force that impedes electrons in an electrical current flowing through a conductor. Explore the causes of electrical resistance, the various factors that can affect the resistance of different objects, as well as the practical applications of objects with high resistance.

Ohm's Law: Definition & Relationship Between Voltage, Current & Resistance

9. Ohm's Law: Definition & Relationship Between Voltage, Current & Resistance

Ohm's Law describes the relationship between voltage, current, and resistance. Learn about Ohm's Law and understand this relationship, including its importance. Use the Ohm's Law equation to calculate the values of voltage, current, and resistance.

Electric Circuit Fundamentals: Components & Types

10. Electric Circuit Fundamentals: Components & Types

Electric circuit fundamentals include components of two types of circuits. Explore the differences between series and parallel circuits and how voltage, total resistance, and current are affected in each type of circuit when more resistances are added.

What is Electric Power?

11. What is Electric Power?

Electric power and its ability to measure energy in watts has become something that technical and non-technical people can understand quite easily. This lesson considers electric power, watts, current, voltage, resistance, and all of these variables' relation to each other.
