What is Electric Current? - Definition, Unit & Types

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

Like a river current is the flow of water molecules, electrical current is the flow of charged particles. In this lesson, we're going to explore what electrical current is, what causes it, and that, unlike a water current, electrical current doesn't always flow in one direction.

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

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

Did you know that electrical current is affected by the voltage and resistance in a circuit? In this lesson, we'll use Ohm's law, which tells us how current, voltage, and resistance are related, as we work through several electric circuit examples.

Finding the Electric Potential Difference Between Two Points

3. 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.

What is Electrical Conductivity? - Definition &  Measurement

4. What is Electrical Conductivity? - Definition & Measurement

Why do some materials allow electricity to pass through them while others do not? In this lesson, we will learn what determines whether a material will conduct electricity or not, a property known as electrical conductivity.

What is Capacitance? - Definition, Equation & Examples

5. 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.

What is Electromotive Force (emf)?

6. What is Electromotive Force (emf)?

The electromotive force (emf) is not really a force but a transfer of electrical energy between high electrical potential and low electrical potential. Investigate what emf is and how it is involved in the thermodynamic properties of an electrochemical battery.

Kirchhoff's Law: Definition & Application

7. Kirchhoff's Law: Definition & Application

Kirchhoff's laws can be used to analyze complex circuits. In this lesson, you will learn about Kirchhoff's two laws and how to apply them to circuit analysis.

Insulators and Conductors: Examples, Definitions & Qualities

8. Insulators and Conductors: Examples, Definitions & Qualities

In this lesson, we'll explore the reasons that some materials conduct electrical energy with ease while others block it almost completely. We'll also talk about the property of conductivity and some everyday examples of insulators and conductors.
