Ch 12: Direct Current Circuits in Physics: Tutoring Solution

About This Chapter

The Direct Current Circuits chapter of this High School Physics Tutoring Solution is a flexible and affordable path to learning about direct current circuits. These simple and fun video lessons are each about five minutes long and they teach all of the definitions and principles of direct current circuits required in a typical high school physics course.

How it works:

  • Begin your assignment or other high school physics work.
  • Identify the direct current circuits concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our high school physics tutoring solution will benefit any student who is trying to learn direct current circuits and earn better grades. This resource can help students including those who:

  • Struggle with understanding electric current, electrical resistance, types of circuits, Kirchhoff's Rules or any other direct current circuits topic
  • Have limited time for studying
  • Want a cost effective way to supplement their physics learning
  • Prefer learning physics visually
  • Find themselves failing or close to failing their direct current circuits unit
  • Cope with ADD or ADHD
  • Want to get ahead in high school physics
  • Don't have access to their physics teacher outside of class

Why it works:

  • Engaging Tutors: We make learning direct current circuits simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live physics tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn direct current circuits on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

Learning objectives:

  • Describe electrical current and its causes.
  • Discover the functions of electrical resistance.
  • Study the basics of electric circuitry.
  • Explain how series circuits and parallel circuits are constructed.
  • Accumulate information about Kirchoff's rules.
  • Define resistors and capacitors, and explore their everyday uses.

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.

Electrical Resistance: Definition, Unit & Variables

2. 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.

Electric Circuit Fundamentals: Components & Types

3. 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.

Series Circuits: Definition & Concepts

4. Series Circuits: Definition & Concepts

When you flip a switch to turn your lights on, you are completing a circuit and providing a pathway for electrons to flow. In this lesson, you'll learn how connecting devices in a series along that circuit affects the current and resistance throughout.

Parallel Circuits: Definition & Concepts

5. Parallel Circuits: Definition & Concepts

People moving through an airport are similar to electrons moving through a circuit. Parallel circuits are one type of simple circuit, and they get their name from the multiple, parallel paths they provide for electron flow.

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.
