Voltage, Current, and Power Explained - Laying the Foundation for Basic Circuits | Basic Electronics

While voltage, current, and power will soon be second nature to you, before we get into circuit analysis, let's take a moment to explain the relationship between these. Once these are explained, you'll have the foundation you need to understand the following videos in this Circuits 1 series we're creating. So, while in this video we just learn the conceptual difference between voltage, current, power, and energy (volts, amps, watts, and joules), the more important thing is that as we learn more about circuits, you won't be lost by these terms and will be able to understand the new concepts we will be learning.

Voltage across, current through. Got it, thank you sir!

[Logan-mefy]

Seriously, thank you so much. I'm 2 weeks into my Circuits 1 and Digital Logic classes so your channel has been a huuuge help.

[LittleMan]

Great explanation! I had seen people use the water analogy before but it was always more confusing than helpful, not this time.

[AwesomeDooshi]

Greetings sir!!! Just wanted to say that out of all the other videos which made voltage and current concepts even more complicating, your video was really very helpful. Thank you very much 🙏

[ESwitchInc]

Bravo! You're excellent at explaining things in a simple, easily digestible manner!

[mayaq]

At last a simple explanation, thanks!!

[kero]

That was so clear and easy to understand. Thanks

[Victor-E-]

This great. The water example never used to work for me, but it does once you added the work and power aspect. Thanks!

[dhliu]

oh my god, your explanation is SUPER SUPER easy to understand : )

[cubbyhoo]

I have just found your channel and I just want to say your very inspiring and are an exact example of why I want to be an Electrical Engineer. I am starting back at University in Glasgow in two weeks so I am really excited and just wanting to get started. Any advice on some projects I could do in my spare time?

Keep it up, your calm methodical style is exactly what I need to hear! Engineering can be a bit intimidating!

[anjanawijewardhana]

This is very simple to understand you're a great teacher 🤟

[yazeedmansari]

Thank you for this amazing simple helpful explanation. I'm 2nd year student and used to have problems with voltage "across" and current "through" 😂😂. Anyways, keep up this amazing content🔝👏🏼.

[armankhan]

Great Channel the way of explaining is amazing 👏 I love this channel thank you soo much 😍

[makfathi]

Thanks for your passion while explaining this :)

[iwantagoodnameplease]

I think that hand zoom should become a signature component of all your videos.

Ps I like the detail on the waterwheel of putting the fall where the paddle actually is! What's the electrical equivalent of that in the hydraulic analogy? 😉

[skanderbenmrad]

From Tunisia. Very good exemple. The water. No best to explaining.

[suleimanmuhammedhady]

I have been searching for simplest explanation of volt current and watts until I came across your video. It well explained I love your work. One question though Volt vs Amps which most important in solar energy that is in charging batteries. I will be very grateful if you respond. Thanks

[billjon]

You had a very clear analog that made me understand the relations a lot more thank you very much. 👍

[nikteckreviewsandtips]

Wow, where has this channel been all my life in school, . 😭😭

[danialmohammadian]

thank you so much, for your explanations.👌
