Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Holy crap this literally saved so much of time. Rather than going through threads online about my question, which is: "Why are voltmeters connected in parallel and ammeters connected in series?" , i just came across this really helpful video that absolutely made sense to me. The explanation was just straight forward: Ammeter, measuring the current through the wire while Voltmeter: measuring the voltage between two particular points. Thank you so much for putting effort into your videos to help those in need. Great job.

@bmzaron713 2 жыл бұрын

great video.. If anyone was wondering/ didn't know, placing the probes at any one spot of the circuit would give you a reading of 0v since the two probes are measuring the same energy potential.. So if you measure before the load/resistor of a 9v battery, you would have 9v-9v = 0 or if you measure post load/resistor/ (i.e. neutral wire) you would for all intensive purpose have 0v -0v = 0v.. This is why you can hang from power lines and not get shocked; however, once you touch any conductor that is connected to the earth it would be really bad..

i am so so so happy i found this video all does circuit diagram saying V is connected in parallel and A is connected in series. i never full understood. i always tried to imagine it but still confused me but when i watched this video it was all clearly the part that explained the iceberg is when you said 'the component E.g wire, you want to measure the current of, has to be disconnected apart from eachother, then connect the ammeter at the two side(left-Right) ' that sentence only explained the word in ''series'' that i hadn't understand. Thank you.

I have a question you might be able to answer. I have read a few articles about how a clamp-on ammeters works. Because you don't have to bridge your circuit with the meter I understand it measures current differently than how it's explained in your video. How can it accurately measure the current through?

Well, to measure a battery's voltage, you need to put the voltmeter in series with it! (though this is pretty much the only use case, and it's also in parallel, since it's the only device connected!)

@altuber99_athlete 6 жыл бұрын

David D29 That doesn't even make sense becauae the current will divide into each resistor, thus it won't be the same for each, thus you can't measure because that's illogic.

@vainfate6275 5 жыл бұрын

You would measure the wire at the return cable to the source, since the parallel circuit will pass all the current back to the source.
