What Is A Shunt Resistor, How Does It Calculate Current & How To Make One (DIY)

Thanks brother.
By the way this jumper wires affect the measuring because of the there resistance.

Continue doing...love the passion

table for check ohm per awg no.
AWG 22 54.8 ohm /1000m

Can I donate a ruler or a tape measure?

just starting electronics and this was very helpful.i am advised I need a shunt resistor or resistance to get good component trace on scope.
I am trying to setup an oscilloscope with a built in waveform generator to produce visual of component curve traces.
does the component bing tested need a certain value shunt resistance ,or do I have to try several resistors to see what gives best visual trace?
thanks

Really well explained. I understand how it works now, thank-you. I've subscribed. 👍

Good vid. The reason why the calc is a bit off is because you measure in between/halfway the wires and clips. The cables and clips you are using also have some resistance especially at a higher current. When you put the shunt at the beginning of the wires it will be more accurate and measures the current thru the whole circuit (with all the losses).

The accuracy of the displays on similar power supplies may not be very accurate at all values. I suggest a 4 wire measurement where you measure the current and voltage to eliminate the influence of the power supply display accuracy. Nice work.

why can't you just put the multimeter in series to get the circuit current, 690mA is quite high - most multimeters will even have a micro ammeter setting won't they?

All the dotty professors and technophobes on utube cannot explain it better than you have. Well done.

The subject of shunts has confused me for ages....but not any more 👍Very well explained. Thank you.

Awesome video thank you

Great video

I made it with the same wire and it shows 5.2 millivolt voltage drop can I use it

You have explained the what, how and why of shunts brilliantly. I finally understand! Thank you.

Loving the Ohm’s Law example. The basis of all electronic understanding. Another great video Hamed.
