      Hi Anuj! We have a few videos up that discuss tips for being an EE student in this playlist - ua-cam.com/play/PLfYdTiQCV_p45pqQC6KytNYmBexo7amQz.html Hopefully you find these interesting and helpful!

    Sir, I saw your Discord and saw you have tutorials on youtube and hence why I'm here. I'm the type that asks a LOT of questions. I want to know if the discord is a 'safe' place I can ask as much questions as I want even if it's extremely basic. I'm at the point were I want to actually understand and not just do stuff and pass exams, I need to understand what I'm actually doing to apply them in real life. Thank you.

      We try to make it a safe place, our first two rules are actually about being nice and keeping it a good environment. Thus far, I'd say it has been successful and I hope it continues to be.

    So, the force that drives electrons is repulsion rather than attraction from the positive pole? Does this mean that if we connect a wire to the negative pole of a battery, there will be some current flowing through the wire without a connection to positive? Sorry for the dumb question.
    And another one: Is it helpful to imagine the electron movement like Newton's cradle? Is it safe to assume that it is the energy that is transfered so fast, rather than the actual electrons?

    • @CircuitBread
      @CircuitBread  Рік тому +1

      It's both! Electrons repel each other AND are attracted to positive charges. And if you connect a wire to the negative pole a battery, it will most likely have a current flow through it - kinda. The wire will immediately come to the same voltage potential as the negative pole of the battery by transferring a tiny amount of current and then it will stop. Unless there's a significant voltage difference before they're touched, it won't be noticeable or perhaps even measurable. But there won't be a consistent current flow unless there's a full path, meaning that it needs to be connected to the positive end of the battery to actually have current.
      Yes, that's a great way to think of it - the electrons are moving but more importantly, it's the energy that is transferred quickly. Actually electron movement is quite slow.

    Could you help by doing some problems using both conventional and electron flow

    • @CircuitBread
      @CircuitBread  4 роки тому +3

      We're still planning our basic circuits tutorial set which we're hoping to start in a couple months. When we do that, our plan is to do some videos specifically to work through problems and give examples of how to do that. We will only be using conventional flow when doing circuit analysis, though. The only time that you need to worry about electron flow is when working with microelectronics at a device level. So if you watch our semiconductor videos, that's when the electron/conventional notation can be confusing. Otherwise, at a circuit level view, you don't need to worry about electron flow.

    Uhm. You ask what is causing those electrons to move but then switch to explain that current and electrons go in opposite directions. Did I miss it? Thanks, nice video nevertheless.

    Hi. The being opposite of "current flow" and "electron flow" is confusing. What is the "current" exactly? Electron flow is not equal current?
    Can you explain this widely in another video pls? Thanks.

    • @CircuitBread
      @CircuitBread  4 роки тому +2

      Hi Nusret! I'm not sure if this deserves a complete video but let me see if I can explain easily here. Current flow is the flow of electrons but defined to be in the opposite direction. That's really it. Ben Franklin knew that there was a flow of something but he didn't know which direction, so he guessed and he guessed wrong. So all circuit theory is defined with the assumption that current flows from positive to negative. But electrons are actually flowing from negative to positive. On a happy note, except for in semiconductor devices and maybe electromagnetic theory, you never really need to worry about electron flow, just focus on current. But, again, they are the same thing, just defined in different directions. Let me know if that helps or if I am just being even more confusing!

      @@CircuitBread Hi. Thanks for your detailed explanation. Well, as far as i understand, briefly you say : " Never mind details, just know that current flows from positive to negative" :) I've already knew it since my technical school,about 30 years, just wondered more detail. But better not make myself more confused and let me go ahead with what i learned so far! Really appreciated mate! You are a good man! Have a great day !

    When u say Higher voltage to lower voltage, do u actually mean positive to negative? 😊

    • @CircuitBread
      @CircuitBread  Рік тому

      Actually, that was purposeful! While we often say positive and negative when dealing with voltages, once you start working with circuits that have multiple voltages (including negative voltages), it's more accurate and easier to talk about the voltages in regards to their relative levels. But positive and negative terminals is a great simplification that works with many, many circuits.

    What happened to our multi meter if we measure the 2000V (DC) but maximum capacity of meter is 600V
    My Digital multi meter is not working after this.

      You probably fried your multimeter, especially if it's 1400V over the max capacity. Sorry, you probably just need a new multimeter...

      Hi David, I think it must be a UA-cam issue. You're one of two comments of this nature in a 12 hour period and we've never had anybody mention this problem before. And it is synchronized for us now, so it must've been temporary, whatever it was.
