would i be defined as retarded If I have the inability to retain all this information? I understand it perfectly. I always have but I seem to forget everything I watch Within 5 minutes. It's the reason I have to watch this video over and over and over again When working with electronics are wiring one the most painful things to admit for example is while i do learn from my mistakes, i almost always forget what ive learned an is the reason why i always repeat my mistakes. its extremely depressing. If you can't remember what you've learned or understand is it any different from not learning or understanding? but i do eventually remember it just has tolo be drilled, id orolly have to watch this video about 30 times before i can remember it all, hence the number of mistakes repeated in life. i hate playing that victim card but its all true

i have a question, why do the volts stay the same throughout the entire circuit even when the resistors are affecting the flow, if you measure before the first restrictor ( by using a multi meter first wire ) to the end of the last resistor ( last wire ), its somehow still 9v. i know that the resistor restricts energy flow but if individually it can be seen that the flow is lesser while the flow is normal altogether from both resistors. how does that differ from just measuring together rather than individually?
i thought maybe it speeds back up when left unrestricted but measuring (via multi meter) from before first resistor and after last resistor will give you 9v still even though according to my idea its basically imitating a long individual resistor.
im confused in my head Dx

The Engineering Mindset I have a question. If at 8: 09 the Voltage drop accross the resistor is 9 Volts, then doesn't that mean that the circuit has lost all of it's potential difference and then there is no longer any current running through the wire after the resistor because there is no longer a difference in voltage? Thank you for your consideration of my question, I am really stumped and have throughly enjoyed your videos enough to want to endorse you. That's how much I appreciate you

Can anybody help please? Does it matter where you are going to place resistor? I mean would it make difference if I place resistor after the buld or before the buld, so it doesn't burn out?
I was thinking that you have to place resistors close to negative end of battery where the electrons flowing from, and before the bulb, but in the video I can see that resistors are placed after the build relative to the current of electrons.
Please, help to clarify)

Thanks Paul,
I have a question, if we apply the same concept about more resistance gives less current, into a circuit in a house.
Why when we have a lot of items working in the same time (resistor is high, the current in the circuit gets overloaded and the circuit breaker trips. Shouldnt the current passing that circuit be less due to the high resistance? Which means CB should not trip. Hope my question make sense

7: 32 you show an animation of a resistor and electrons flowing through it. you say, the same amount of electrons enter and exit. wouldn't this mean, the same current? But according to I = U / R, current is indeed altered through a resistor. Does the animation visualize the so called energy loss of the electrons? How can electrons lose energy, if not by slowing down?

This is the best! I used today at work when I had to convert 2V signal to 4 mA signal because the sensor was taking mA and our controller was able to send only 2-10VDC signal and I wasnt sure how to connect the resistor. Then I watched the video at work, understood everything and everything worked after I placed the 500 Ohms resistor in series. Thank you very much!

I understand that the voltage is the same at the start and end regardless of the amount of resistors in series, because voltage in series gets added up. However, connecting one end of a resistor to another one (still in series, but, at the same time, connecting that same end to bypass the next resistor (putting them in parallel) what would happen?

How is conventional current easy to understand? It makes things more complicated. Working on car wiring and positive/ground is reverse electron flow which is how my brain thinks. Had me asking the question, why does the negative run into the body of the car. Well I'm an idiot, just found out the positive is actually negative and visa versa

i could be wrong but i believe you made a mistake to the final question answer on your website. you used the first method but forgot to do voltage squared so you listed 9v / 460 ohms and got the answer of 0. 0195A. but if you do 81v/ 460 ohms the answer is 0. 176A. am i confused or did you make a mistake. sorry just trying to understand

Sorry if this is a confusing or dumb. When he talks about watts in the end of the video, is he talking about it being the power consumption of the all the resistors? Or if he were to put a light bulb on to the circuit, That the bulb would be powered with how ever many watts with a 9V battery at the end of the of the circuit.

Currently in Army BET lab, and this stuff went over my head today. Probably would have helped if it wasn't a class done completely by computer with minimal instructor guidance, but that's a complaint for the AAR.
Thank you so much for making these videos- I might actually graduate this course.

I still dont understand why is the current the same throughout a series circuit?
His explanation is one path, one direction. .. , but its more intuitive to assume the current would be greater value before it hits the first resistor and smaller value after the last resistor.

I'm a bit confused why don't the resistors effect the amps? Like if electrons are hitting things on the resistors and amps is just coulumbs which is the amount of electrons flowing shouldn't that drop due to the fact that the resistors are destroying some of the electrons?

Question about resistor in series: when you have a high value resistor and a lowe value resistor, does it mstter which resistor is first? Im thinking if you yave the lower value resistor first, couldnt that burn up? If not, why?

I suspect there are a lot of people here who know a lot more than myself. At the end at the test your knowledge problem I thought I would have to deduct the 2V the LED needed. Yet it seems that is not correct?
Anyone?

I started watching your Basics series and, as someone whom is nowhere a genius when it comes to electricity, this made questions I've had for decades seem so common sense. Thanks for explaining things in laymen's terms!

This is a great series of videos. Easily followed. Pretty thorough.
But, wow! Are they ever repetitive. I guess you wanted every video to stand on its own but I sure would prefer to have a series of trimmed videos.

Excellent video sir, kindly let me know this, IS that any time limit for dc current measurement in SERIES like 10 seconds or i can leave my multimeter connected in SERIES while battery is charging the whole time?

Sir why ammeter show same value at any position in seris circuit. acc. To me after resistance current should vary because resistance is inversely proportional to current. Is am I right if no then why?

Interesting thing just happened. I tried to test out the equation with my breadboard, and using a 9v batter and 10 ohm resistor burnt out my resistor. Anyone have any advice on what I did wrong?

Add the ohms together and that equals 460 ohms. Current = Voltage / Resistance. 9 volts / 460 ohms =. 019 amps. So the answer is 19 milliamps.

YES, the current less than 0. 002A coz the total current was 0. 019A. Or approximately 0. 002A and the LED LIGHT comes On.
