Electronics 101

Posted by Paul Campbell on June 01, 2013 in Talks tagged with

I’ve included here the electronics1 talk I gave this week as a PDF

Remember the simple takeaways from this talk:

- the relationship between voltage, current and resistance – in particular bigger resistors mean less current

- capacitors pass AC and block DC

- inductors block AC and pass DC

- bipolar tranistors control a large amount of current with a small amount of current

- FET transistors control a large amount of current with a voltage

Please go and play with the excellent circuit simulator at:


try playing with resistors, current and voltage – and of course grab some and a meter at Makerspace and have a play

Week 2 talk electronics2 is also here as a PDF – transformers, diodes, power supplies, op amps and timers
