Thank you! Your vídeo helped me a lot!
but this meter doesn't have a fuse on 10A jack lol.
anyway starting from the largest range is really good habit and few people talk about that these days
Why should the meter have a fuse on the 10A jack?
Just curious
@@niranjanaarulnambi7309 Well this happens from time to time - measuring voltage after measuring current , the probe is still in 10A jack but you forget to plug it into Volt jack. Here your multimeter actually forms as an ammeter instead of a voltmeter as you think it would be. Ammeter has really low internal resistance and connecting an ammeter across voltage source (to measure voltage) performs a short circuit, causing arcs and damage . But with a fuse in series, it burns when current is too high to stop this short circuit and to protect both you and your stuff.
so always use ORGINAL MULTIMETER
Yes thanks for that tip
@@niranjanaarulnambi7309 Damned if i know. Im learning
Or you could measure the voltage drop across the LED, and use Ohms law to calculate the current.
I like ur expression bro Mr Tuitor
Thanks.
Thanks
Thanks clear tutorial
Need descriptions of that code here in comment so we can watch full video.kindly share it here
Not quite sure if this is what you were asking for, but here is our full length tutorial video: ruclips.net/video/ts0EVc9vXcs/видео.html
Free at harbor freight! Oh yea the good old days- now have to step up and pay $4
do u know how we can directly measure the current of a battery?
yes i also wondering how it is done.... if we directly connect the multimeter probes to the battery +, - then it shows some value then the value is constantly decrease..... i think it is not the correct way... please help if anybody have any resources to know that...
You need to connect the battery to a load (like a resistor) and put the multimeter in series with it. If you connect the probes directly to the battery and set the multimeter to measure current, you are effectively short-circuiting the battery and will blow the fuse in your multimeter.
@@Science.Buddies thank you for your clarification.... you saved my multimeter.....
What if you get zero in 10 amp
I'm try to adjust current for my buck converter. Does it require to have a load in series?
woah i have this same multimeter
They one made millions of them
My multimeter current range digits auto increase without prob touching..
Anyone have solution
You had change the prob
Yup and he gave no explanation as to why he changed it.
He did explain. Where he initially placed the red probe is where you do when you're measuring current in the range of ampere(you can see the marking as 10A). The latter is for small currents, that is mA.
Does it mean that your led consumes 23 mA per second?
amperes (A), the unit of electric current, measure flow of charge (coulombs) per second, so mA (milliamps) is already "per second."
Ok, thank you for the explanaition. So just to confirm, the consumption of a single led is 23 Ampers?
23 milliamps. One milliamp (mA) is one thousandth of an amp (A).
Meter name
This is a DT830L meter (look closely at the meter in the video and you will see the model number).
This is terrible shit.
Buy/use at least e.g. UNI-T UT33
Harbor freight! Oh yea
Then how to measure ampere-hour (ah)
That is just the amount of current per hour so its not really measureable
I feel retarded now. I was getting frustrated it wouldn’t measure amps. I bought this little cheapo thing specifically for that because my good one doesn’t do that. I’m a contractor and only deal with AC so I’m unfamiliar with measuring DC.
