Ch 20: Electronic Circuit Elements for the MCAT: Help and Review

About This Chapter

The Electronic Circuit Elements chapter of this Medical College Admission Test (MCAT) Help and Review course is the simplest way to master electronic circuits. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of electronic circuits.

Who's it for?

Anyone who needs help preparing for the science section of the MCAT exam will benefit from taking this course. You will be able to grasp the subject matter faster, retain critical knowledge longer and earn better grades. You're in the right place if you:

  • Have fallen behind in understanding the components of an electric circuit or the relationships shared by voltage, current and resistance.
  • Need an efficient way to learn about electronic circuit elements.
  • Learn best with engaging auditory and visual tools.
  • Struggle with learning disabilities or learning differences, including autism and ADHD.
  • Experience difficulty understanding your teachers.
  • Missed class time and need to catch up.
  • Can't access extra MCAT science preparation resources at school.

How it works:

  • Start at the beginning, or identify the topics that you need help with.

Electric Circuit Fundamentals: Components & Types

1. 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.

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.

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.

What is Electric Current? - Definition, Unit & Types

4. 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.

Voltage Sources: Energy Conversion and Examples

5. Voltage Sources: Energy Conversion and Examples

We use them every day, but no one really gives them much thought. What are we talking about? Why, voltage sources, of course! Batteries and generators are two of the most common sources of voltage that power our daily lives. We'll look at them in detail to see how they work.

What is Electric Power?

6. 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.

Faraday's Law of Electromagnetic Induction: Equation and Application

7. Faraday's Law of Electromagnetic Induction: Equation and Application

Electromagnetic induction allows us to induce voltage with the movement of a magnetic field. Credited to Michael Faraday, this discovery was not only groundbreaking at the time, but it has since led to many applications in everyday life.

Capacitance: Units & Formula

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.
