Insulators and Conductors: Examples, Definitions & Qualities

1. 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.

What is Electric Current? - Definition, Unit & Types

2. 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.

Electrical Resistance: Definition, Unit & Variables

3. Electrical Resistance: Definition, Unit & Variables

We'll take a shopping trip to the mall to learn how electrical resistance works and how it is affected by resistivity, conductor dimensions, and temperature. We'll also take a look at several common appliances that take advantage of resistance to function.

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

4. 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.

What is Electric Power?

5. What is Electric Power?

Power is a word we use all the time, but do you really know what it means? We'll look at how electrical power relates to voltage, current and resistance and how knowing that relationship can help you in everyday life.

Applying Kirchhoff's Rules: Examples & Problems

6. Applying Kirchhoff's Rules: Examples & Problems

Ohm's Law can be useful for analyzing simple circuits, but when circuits are more complex, as they often are, we can instead analyze the circuits using Kirchhoff's rules. Learn about Kirchhoff's rules in this lesson.

Resistor-Capacitor (RC) Circuits: Definition & Explanation

7. Resistor-Capacitor (RC) Circuits: Definition & Explanation

Resistor-capacitor (RC) circuits are everywhere because they are useful in our everyday lives. The current in these circuits varies with time, making them both practical and common in many types of electronic equipment.

Impedance in Alternating Current Circuits

8. Impedance in Alternating Current Circuits

In this lesson, you will learn about topics that include the difference between DC and AC circuits, the use of rms values, definitions of impedance and reactance, and calculations involving the reactance of capacitors and inductors.

R-L-C Series Circuits

9. R-L-C Series Circuits

After watching this lesson, you will be able to explain what an RLC series circuit is and use related equations to solve simple problems. A short quiz will follow.

Alternating Current Power Calculations

10. Alternating Current Power Calculations

After watching this lesson, you will be able to explain the difference between AC and DC circuits and calculate AC current, AC voltage and AC power using both rms values and peak values. A short quiz will follow.
