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.

Electric Circuit Fundamentals: Components & Types

2. Electric Circuit Fundamentals: Components & Types

Electric circuits can be configured to power several loads, such as light bulbs, in series or in parallel. In this lesson, we'll look at both types of circuits and see how the voltage, current, and resistance are affected by installing additional loads.

Types & Components of Electric Circuits

3. Types & Components of Electric Circuits

Learn about electrical components and types of circuits. By the end of this lesson, you'll be able to explain what components like bulbs, resistors, and capacitors do. You'll also be able to compare and contrast series vs. parallel circuits and DC vs. AC circuits.

Electrical Circuits: Energy Transfer & Conservation

4. Electrical Circuits: Energy Transfer & Conservation

After completing this lesson, you will be able to explain what an electric circuit it, how energy transfers in a circuit, and how circuits relate to the conservation of energy. A short quiz will follow.

Finding the Equivalent Resistance: Series, Parallel & Combination Circuits

5. Finding the Equivalent Resistance: Series, Parallel & Combination Circuits

How does resistance impact the way that electrical currents flow through a circuit That's what we are exploring in this lesson. We'll check out resistance in the three main kinds of circuits and practice calculating this value.

Examples of Complex Series & Parallel Circuits

6. Examples of Complex Series & Parallel Circuits

Circuits are a way to use electrical energy to do something useful. In this lesson we will go through a few types of series and parallel circuits designed to do something specific.

What is an Ammeter? - Definition & Function

7. What is an Ammeter? - Definition & Function

In this lesson, we'll learn what an ammeter is and what it has to do with electric circuits. We'll also talk about the proper ways to connect an ammeter in series and parallel circuits.
