Electrical Fundamentals
The flow of electrical power or charge.
What is Electricity.
The three elements of a circuit.
What are power source, load and path?
V=I*R, I=V/R, R=V/I
What is ohm's law?
An electronic measuring device with a digital screen, containing a voltmeter, Ammeter and an Ohmmeter
What is a Digital Multi-meter
This turns electrical energy into heat energy.
What is resistor?
A material that allows electricity to flow easily.
What is a Conductor?
