Electric Field Intensity

The Electric Field Intensity Video Tutorial discusses the mathematics of electric field. Mr. H introduces the two equations, explains their meaning and use, and describes how to decide which equation to use. Mr. H also discusses the rules for determining the direction of the electric field vector.

The video lesson answers the following questions:

1. What are the mathematical equations associated with the electric field intensity?
2. How do you determine the direction of the electric field vector?

Additional and Related Learning Tools

Concept Builder: Electric Field
A Concept Builder provides an opportunity to put to practice the understanding of a concept while solidifying and refining that understadning. This Electric Field Concept Builder has more of a focus on the mathematics of electric field ... you'll probably be there soon.

Concept Builder: Electric Field Strength
Another Concpt Builder. This Concept Builder also focuses on the mathematics of the electric field and is a great follow-up to this video.

The Calculator Pad, Static Electricity Chapter, Problems #15-21
You can't beat the Calculator Pad for providing practice with solving Physics word problems. Each problem set contains a variety of problems with answers and audio-guided solutions. Start with #15-21 of the Electrostatics problem set.

Minds On Physics the App, Part 4, Mission SE11 in the Static Electricity Module
Minds On Physics includes interactive questioning modules that provide a rigorous workout in careful reading, analytical thinking, and conceptual reasoning. Mission SE11 from our Static Electricity module is all about the electric field concept. Put on your work-out clothes and get started.

Teacher Resources

Curriculum Corner, Static Electricity Section
Our Curriculum Corner is composed of a collection of Think Sheets. Each one makes for a great component of any Lesson Plan. They work great for both independent practice exercises and cooperative group exercises. The following Think Sheet makes a great complement to this video:
Electric Field

The Calculator Pad, Static Electricity Chapter, Problems #15-21
You can't beat the Calculator Pad for providing practice with solving Physics word problems. Each problem set contains a variety of problems with answers and audio-guided solutions. Consider assigning #15-#21 of the Electrostatics problem set.

Electric Field Concept Builder
A Concept Builder can be one of the best tools to deepen a student's conceptual understanding. And when combined with a Task Tracker subscription, you can track students' progress on the various parts of the activity. This Concept Builder pertains to the mathematics of electric field ... a perfect follow-up to this video.

Electric Field Strength Concept Builder
Here is another Concept Builder pertaining to the mathematics of electric field. Another great follow-up activity.

Physics Interactives, Static Electricity Chapter, Put the Charge in the Goal
Nothing brings the concept of a charge exerting an influence at a distance better than this simulated game. Students place charges on the screen to guide a charged object around obstacles and into a goal. Good phun. Good thinking and problem-solving. Good learning.

Minds On Physics the App, Part 4, Missions SE10 to SE12 in the Static Electricity Module
Minds On Physics is not for the meek-hearted. They are interactive questioning modules that provide a rigorous workout in careful reading, analytical thinking, and conceptual reasoning. Missions SE10 through SE12 from our Static Electricity module pertain to electric field ideas.

Physics Classroom Tutorial, Static Elecricity Chapter
It reads like a book ... but much better. Our Tutorial section has long been the most trafficked section of our website. And for good reason - it's understandable. We recommend leaving links to specific pages on your Course page. The following pages will be helpful complements to this video:
