(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, […]
