What is Electric Current? What is a Short Circuit?

Electricity is a powerful force that is essential to our modern way of life, but it can also be incredibly dangerous if not understood and handled properly. In this beginner's guide to electric current and short circuits, we will explore the basics of electrical systems and the dangers of short circuits.

First, we will discuss what electric current is and how it works. We will cover the fundamental concepts of voltage, current, and resistance, and explain how they interact in electrical circuits. We will also discuss the different types of electrical systems, including direct current (DC) and alternating current (AC).

Next, we will dive into the topic of short circuits. A short circuit is a dangerous condition that can occur when an electrical current flows through a path of least resistance, bypassing the intended load. This can result in overheating, sparks, and even fires. We will explain what causes short circuits and how to identify them.

We will also discuss the importance of electrical safety and offer tips on how to prevent short circuits from occurring. We will cover proper wiring techniques, the use of fuses and circuit breakers, and the dangers of overloading electrical circuits.

Throughout the video, we will use clear and concise language, and provide helpful illustrations to make the topic accessible to viewers of all levels of knowledge. Whether you are a beginner looking to learn more about electric current and short circuits or an experienced electrician looking for a refresher, this video is for you.

In conclusion, electric current and short circuits can be complex and dangerous topics, but with the right knowledge and precautions, they can be managed safely. This video aims to provide a solid foundation of understanding for anyone interested in learning more about these important concepts.

Today is my birthday and tomorrow is «pre-exam test» in physics. So this is the best birthday gift I could get! It’s literally the only chapter I need to practise on before tomorrow. Thank you so much Jason, this comes at perfect time as always! 👏

Despite being taught electricity/currents/volts etc in Physics at school, your videos are the first time I really understood it. Much appreciated.

[patriciaarney]

You are an amazing teacher, slowly making my way through all your videos. You can tell someone understands their subject/ trade really well when they're able to break it down into its most basic components and make anyone understand it. Thank you
🙏

Professor Math and Science Tutor, thank you for an excellent explanation of Electric Current and Short Circuits in everyday Electrical Systems. For students in Electrical Engineering, Electrical Current/Short Circuit is a very important topic to learn, due to the dangers of these two systems. This is an error free video/lecture on YouTube TV with the Math and Science Tutor.

Here's a couple of statements that are true that I hope you will explain. All the available voltage should be used up across the load. Adding resistors in a series circuit is different than adding up the resistors in a parallel circuit correct. Thanks for the great videos and info.

[amenkonsult]

Very good teaching, can be understood by non science / engineering students.
Thank you.

[anthonygregg]

these are amazing lessons when we have demonstrations. Its is incredibly useful and easier to understand. you are a fabulous teacher sir.

High speed tutorial this one is, mr Gibson, many joules were burned during the making of this video 😆 thanks for all of your work, I just subscribed to your website, it's teaching me a lot. Best regards from the Netherlands.

Where has this channel been all my life?! I'm learning all kinds of things. Thank you very much!

[frankroper]

I have watched maybe 5 videos where Jason has explained the rules of voltage and current and resistance so it is starting to sink in that he thinks this is a very important building block to understand electricity! Hope you have a great Father's Day Jason!

Another terrific lecture, Jason. I remember watching freight trains being shunted when I was a youngster. When another freight car was shunted on to the end of a mile long train, the jolt would be propagated through the entire length of the train to the locomotive in a second or two even though the actual movement of each car was very small. I think of this when I think of the difference between the speed of electrons in a conductor and their speed of propagation. A small point which I'm sure you'd be aware of: the resistance you measured in the cold light bulb in the circuit you showed was quite low, and didn't account for the current difference using Ohm's law. The resistance would have been much higher when the light bulb was actually illuminated.

Happy new year! 🎉 Thank you very much for your time and commitment!

[bshwin]

Excellent, really love listening to your presentations.

[ectcool]

I enjoyed the physics presentation on electric current, and what is a short circuit.

[kennedywambugu]

Very informative in a simplified way. Thank you

[RAMlaw-Norcal]

Fascinating stuff. You are an excellent educator. Thank you.

[SuperKendoman]

Sir, can you later do a video talking about flemings left hand and right hand rule? I love learning about electricity and magnetism. It's fascinating to me. Thank you for the great content and for taking the time out of your busy life to teach us

[jimedgar]

Absolutely brilliant! Thank you so much.
