T4E – Voltage and Current

Hello! My name is George Crump. I’m the Electrical Technology instructor here at the Kansas City Kansas Community College in the Technical Education Center. Today I’m gonna be talking about how to determine the voltage at your home on the service panel and also give you some safety tips. In addition, I’m going to show […]

Energy Experiment: Electricity Flow through the body

Hello! Today I will be conducting energy experiments to do with the electricity of the human body. Electricity in our bodies literally holds us together. Hopefully I will show you the power of the electricity flowing through our bodies. For this experiment you will need: – One short length of galvanized steel metal; – One […]

Basic Electricity – Resistance and Ohm’s law

In this video I’m going to talk about electrical resistance, ohm’s law, and how to pick a resistor to limit current in an LED circuit. In previous videos I talked about how voltage can behave like a pushing force, pushing electric current around a circuit. But in one example I connected an LED straight to […]

Electronics Tutorial #1 – Electricity – Voltage, Current, Power, AC and DC

hello everyone and welcome to this tutorial we’re going to start getting to the basics of electronics now for this first video what we’re going to do gonna and have try and have a basic understanding of electricity and how electricity works and the basic components of electricity now i’m going to start off with […]

Basic Electricity – Power and watts

Today I’m going to talk about watts and electrical power. In my previous video about voltage, I talked about how amperes is the number of coulombs flowing per second, and volts is the number of joules of energy transferred for each coulomb of charge that flows. I had an example set up where I had […]

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. […]
