Metal detector (Garret AT Pro) target discrimination explained

A few years ago I got myself a new hobby: metal detection. For me, the fun is in finding things that are interesting rather than valuable. So to find of a condom package from the 1980’s is just as exciting as finding old silver dimes or an 18th century musket bullet. It is about imagining […]

Review of all Electricity and Magnetism Dimensions – AP Physics C

Bo: Hey guys. Billy: Hey Bo. Bobby: Hi Bo. ♫ (lyrics) Flipping Physics ♫ Mr. P.: Ladies and gentle people, the bell has rung, therefore class has begun. Therefore you should be seated in your seat and ready to review electricity and magnetism dimensions, because dimensions are your? Billy, Bobby, Bo: Friends. Mr. P.: That’s […]

(2 of 2) Electricity and Magnetism – Review of All Topics – AP Physics C

Mr. P: Ammeters and voltmeters. An ammeter, you need to put in series, a voltmeter, you need to put in parallel. In order to measure the current, in order to put it in, you need to have it in series, right? In order to have little change to the circuit, you need to have as […]

How to Make a Shunt Current Sense Resistor

Hi, I want to make a *beep* I said shunt! I want to make a *shunt* current sense resistor. Basically the way we measure current is by converting it into voltage passing it through a known resistor which we call a shunt and so the current is the measured voltage divided by the known resistance. […]

Inductor basics – What is an inductor?

Welcome to my first video about inductors. So, what is an inductor? Generally speaking an inductor is a device that temporarily stores energy in the form of a magnetic field. Inductors are usually just coils of wire and one of the basic properties of electromagnetism is that when you have current flowing through a wire, […]
