How To Test Amperage / Amp Draw and properly measure and fuse a circuit

I show how to test how many amps an electronic device pulls with a standard multimeter. To get wattage multiply amp x volts...

Perfect video!! No headbanging music, no introduction. No mumbling. Clear and concise instruction. All YT videos should be this good. Thank you.

Right on point. I hate forgetting stuff, but I love finding simple quick explanations that refresh my memory like this one. Great job!

I got so frustrated watching an 8-minute video beating around the bush. I appreciate you being frugal with our time. Thank you.

Far out thanks dude, have a great one, quite clear

Great wanted to know how to measure DC amps not just volts.
Really helpful.

Thanks for this informative video. I didn't have my new meter for 10 minutes before blowing the 11amp fuse in it. Didn't know the current had to go through the meter. I thought the meter would be able to know the amp draw on my outlet at home. Just wanted to test out of curiosity. What a dumb move! Appreciate the video

Great video, simple and straight to the point. Thanks for the help!

Good video...Simple and easy to understand...Thanks to the gent that made it.

As for the current issue, yes that meter is reading 80mA. This is a fact. If you are suggesting otherwise I hope you don't wire houses for a living...Other than that, knowing the application is trailer lights, you would take the total amount of current draw from all lights together (however much that may be) and set a value fuse in place that will open if a short occurs (a wire gets pinched, ect.). If one light draws 80mA and they are used in pairs, (160mA or .16A) given they are connected to what looks like 22/24 guage wire, I would say a 250mA fuse would be the minimum value I would install (don't forget about transients) or 500mA fuse max. If more lights are added later, then a fuse value needs to be recalculated. The point is to avoid a fire during a short because chances are the output transistor/relay that is switching that power signal on and off from the auto can source waaaay more current than 250mA. That being said you can get 500mA through that wire all day and it wont get hot, any more will open the fuse way before anything heats up while imposing no limits on current draw from the lights.

Brilliant post, very easy to follow and straight to the point. Thanks for posting this.

Mate, this was an excellent vid, no bullshit or babbling on, just straight to the point...👍😄🙀

[eddieman]

Exactly what I needed to know. Thanks for the video.

[flyryde]

Congrats on 100k!!!! 🙌 well done dude!

It reads 0.08 on the 10 Amp setting that means 0.08 A or 80 mA. 10 A is a huge current that you almost never encounter, especially not in a car. If you are expecting the current to be little you would not use the 10 A setting. That is the highest setting on handheld multimeters.

i melted a multimetre once trying to test the amperage of a battery LOL so I always like to check in on youtube videos to get it right before I do it now

[Jenuin]

Great video. Answered my question. Thank you.

[RTH]

Cheers buddy - exactly what I wanted to know.

[jsmgaming]

Thank you. You saved me from buying 6 gauge wire, lol

[davidkeech]

Perfect video! Using this test at work, I can trouble shoot better tyvm.

[djquixx]

Thank you so much for this. I always wanted to know how to do this
