Open Circuits, Closed Circuits & Short Circuits - Basic Introduction

This physics video tutorial provides a basic introduction into open circuits, closed circuits, and short circuits. An open circuit contains a break in the circuit and does not conduct electricity. The closed circuit is a circuit that conducts an electric current and has a measurable amount of resistance. The short circuit is a closed circuit with almost no resistance which allows a large amount of electricity to flow in the conductor which can be a fire hazard. This video also briefly discusses the purpose of a fuse and a circuit breaker to prevent the formation of a short circuit.

I finally understood the short, open and closed circuits. Every short circuit is a closed circuit, but every closed circuit is not a short circuit, because in closed circuits there is some resistance, and thus the current passage is limited. But short circuits are dangerous, cables can burn 'cause there is no resistance in the circuit. Well done

You are a good teacher. Concise and straight to the point. Well done.

My teachers failed to make me understand the difference among these things..I now understand.. Thanks a lot

A great introduction; I liked especially his explanation of fuses and circuit breakers and his explanation of what makes a short circuit. This lecture was omitted somehow from his electronics playlist - he should include it for sure.

Sir you are an angel. You deliver concepts in a comprehensive manner which makes them easier to understand and grasp. Keep up the good work!

I wish that the teacher explained this in our fundamentals class. When we got further in to class, working on superposition, he was say to "replace one power source with a short." I had no idea what he meant by "short." Thank you for this!

Thankyou for this brother may GOD Bless and Guide you more

[amsib]

That's was so much helpful. Thank you so much.

[deanoscott]

Ideal for what I needed today bud. Thanks.

[pandora]

Thanks for the explanation, now I know how to use the steps for Norton and thevenin theorem with this explanation of open and short circuit haha

[amrshora]

I'm grateful to be here in that kinda issue I've stuck in for a long time, You're amazing!

[vinodkallat]

I see an another video that is not
And this one so easy to
Thanks for your this video

[arifiqbal]

What a simple & beautiful explanation 🎩 🎩 Off.

[Martin-otxj]

Hi there, you really explained very simply. better than any institute and university. thnx

[sdas]

Sir, in close &short circuit, both current flows, then how to check which one is short?

[karam]

5 min video > any 1 hour lecture about this

[javad]

Hi, it was great, I was looking for this article.

[calebesteves]

For the closed circuit with a resistor, wouldnt the wire the current flows in before the resistor melt or smth, or is there a reason this wont happen

[timt]

How to I make a circuit with to motion sensors that trip a light but only the first one tripped will turn on a light ?

[KpopTrashSince]

Omg Thank u so much 🙌🙌🙏🙏
I am a first year engineering student and all your videos help me a lot 🙆🙆
