so is it safe to say that voltage determines current? the higher the potential difference(voltage) the higher the current?
very good explanation….
240P…… we meet again -_-
alguien me puede ayudar a traducir este video a español porfabor o a decirme que dice porfa
if one device in a parallel circuit had longer wire system would there be any change in the voltage on that longer cable? will it increase or decrease or be the same? pls explain
Thank you so so so muchh..!! I struggled to understannd voltage, but this made it lot easier!! Very simple, straightforward, and comprehensible! Well done video.
15 fuckets a second
best information…but it is not like that positive terminal is taken at higher potencial,and here u have taken negative????please,clarify me
@erasynth that’s what i thought about amps at first, but that’s not really how it works. amps are the AMOUNT of charge passing a given point in a circuit per second. not necessarily how fast they’re going. current=q(charge)/t(seconds); speed=d(distance traveled)/t(second). think of it this way, a wider river can allow more water to flow past a given point than a narrower river(if pressure allows it). hope this helps.
fuck sake this guy has taught me everything my physics teacher has been trying to tell my class and I for the past week.
Can you be our new physics teacher?
So amps is kinds like speed and volts is kind of like the power………..if I wasn’t getting a lot of power could I speed it up to get what I need……And if I had to much power couldn’t I slow done the speed my using a resistor to get what I need.
thank you very much this was very helpful….so electricity wants to equal out kinda so thats why it flows to lower potentiol…..but that means the longer you use the the battery the less volts you get out of it …right ….so you only have the voltage the battery says it has right at first and that goes down over time
i got an A at gcse physics this year, and i still learnt a couple of things from this video. it goes to show what a load of crap gcses are
@gullenator1 Ya thats cool. No hard feelings. If I got angry at words on youtube id probly have a lot of problems. I will read into it. I do try to admit when I know I’m wrong. Only human after all. Anywho Good luck and maybe if you don’t mind you could tell me your opinion on your EE course I was thinking of going back to school for something like that. Either that or computer science.
@InsanePorcupine It’s cool. I apologize for being hateful. I know you were trying to correct what seemed like bad information to you. There’s quite a bit of information on non linear circuits. I’m unable to post a link due to You Tube. Google non linear conduction, the first link has some good examples and suggest ohms law, should not be a law, if you are interested.
@gullenator1 and from what ive seen it didnt say that ohms law was false just not practical. Please send me a link explaining how ohms law is well not a law and ill read into it.
@gullenator1 I dont like coulombs i think because its french. I mean they rename everything in french such as email and router. They dont like english so i dont like french. Good luck with your course. I still don’t think more more volts necessarily = more amps as I said in my battery analogy. I harbor no ill feelings towards you I was mainly just pointing out that potential difference is a theoretic number and doesn’t necesarily mean high current. I did read into non linear circuits.
@gullenator1 ok your right about coulombs and if you had read all my comments you would know i rescinded that comment which I made years ago. Still don’t believe that more volts necessarily = more amps. Hence my battery analogy. My main point with the ohms comment is that you need both high ohms and amps to be shocked which i have seen to be true through experiments. I hope though that you don’t believe that a 12 volt battery is actually 14 volts that was ridiculous.
great explanation , you helped me a lot !
@InsanePorcupine 4) A “super low resistance circuit” can and will electrocute you. You are confusing this with the idea that a short circuit made of ideal wires would by pass other elements in parallel. No real circuit will behave this way. Make an experiment and test it you will get shocked. 5) There is nothing archaic about Coulombs they were derived from Coulombs experiment with electric fields. Now please take your junk science elsewhere and stop “correcting” this video.
@InsanePorcupine While the amount of current that can flow is dependent on the external circuit. In situations dealing with the power grid the source can essentially provide an unlimited amount relative to your body. A high resistance circuit is not needed for electrocution only an energized circuit with sufficient voltage and for you to complete the circuit. 3) You don’t need to be the path of least resistance to get electrocuted. The body has more ohms than any circuit in your house.
@InsanePorcupine Ohms law does not apply to non linear circuits, including circuits where the resistance changes with temperature. Don’t just pretend this is not true because it doesn’t fit into your understanding, research it. Now I will address the moronic statements you have made one by one but I doubt it will convince you. 1) Volts are in fact what pushes electric current through you. It is also called electro motive force. Your body is a good resistor, voltage is needed to drive current
@InsanePorcupine With these kind of statements it wouldn’t matter if I was a 6th grader with a good understanding of science I would still be better of than you. I suppose you failed to read or understand the response which is still up stating my credentials. Credentials are meaningless though on the internet. I’ll let your statements speak for themselves. You’ve done nothing but try to rudely correct the professor on this thread and the “help” you give is flat out dangerous.
@InsanePorcupine Let’s recap your moronic statements: 1) ” …voltage is not what pushes a current through you.” 2)” So to sum up if your body has say 50 ohms of resistance an electric circuit will need 50+ ohms to send electricity through you.” 3) “so no volts dont kill amps do but they wont kill you unless there are enough and you are the path of least resistance.” 4) “if you have a super low resistance circuit it won’t electrocute you.” 6) ” I just think coulombs? are archaic and confusing.”
