# Ch 67: MTEL Middle School Math/Science: Electricity

### About This Chapter

## MTEL Middle School Math/Science: Electricity - Chapter Summary

Preparing for the MTEL assessment might require you to revisit topics you haven't explored in months or years. Simplify the process of reviewing these topics by watching videos that prepare you for:

- Defining electric charge and force
- Examining electric force fields and the significance of arrow direction and spacing
- Analyzing Coulomb's law and electric potential
- Describing insulators, conductors and voltage sources
- Sharing your knowledge of electric current, electrical resistance and Ohm's law
- Discussing electric circuit fundamentals and electric power

This chapter provides the resources you need to fully comprehend electricity as you study for the test. Take advantage of the ability to learn from quality instructors via video lessons and submit questions to experts, all from the comfort of your home.

### MTEL Middle School Math/Science: Electricity Chapter Objectives

The primary objective of this chapter is to ensure you're prepared to answer questions found in the physics subarea of the MTEL Mathematics/Science (Middle School) assessment. This subarea constitutes about 8% of the total test and is located in the multiple-choice section. Earning a passing score of 240 or higher on the assessment meets the requirements for the licensure needed to teach math and science to middle school students in Massachusetts.

In addition to reviewing the lessons in this chapter, you can take self-assessment quizzes to gauge your comprehension of concepts covered. A chapter exam is also available to reinforce the lessons. If you have any questions about topics in this chapter, submit them to our experts, who are eager to offer assistance.

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

Have you ever wondered what electricity is and where it comes from? Have you ever been zapped by static electricity and wondered how it got there? We'll answer all of these questions in this lesson on electric charge and force!

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

Did you know that force fields don't just exist in science fiction movies? In this lesson, we'll explore the electric force fields that surround charged particles and how we can draw diagrams that represent them.

### 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 charged particles. The results of his experiments led to what is now known as Coulomb's Law, which tells us how force, charge, and distance are all related.

### 4. Electric Potential: Charge Collections and Volt Unit

In this lesson, we'll find out that electric charges can be rather lazy until something motivates them to get work done. Find out what gives electric charges the potential to do work and how we measure that potential with something called voltage.

### 5. 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.

### 6. 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.

### 7. 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.

### 8. 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.

### 9. 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.

### 10. 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.

### 11. 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.
