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?

Topics for future videos in this series:

  • Ohms law, resistance, power, energy
  • Electronic components – diodes, transistors, FETS, capacitors, digital logic gates, integrated circuits, 555 timer.
  • Series and parallel circuits
  • Op amps and feedback
