  • In this tutorial I cover the following:

    * Some history about electricity / central power stations / electrification.
    * Science of electron flow in a conductor / wire
    * I use fluid dynamics in a pipe to explain voltage (pressure), current in Amps (flow) and consumption in Amp hours (rate of flow).
    * We look at AC (alternating current) and DC (direct current) on the UNI-T UT81B scopemeter
    * We look at how voltage / pressure is required to charge a 12 volt battery
    * What is electricity? / How does electricity work?
