  • what is the recycling story for Tantalum?
     
  • what does the voltage number on the cap mean?

Polarized

electrolytic

capacitor

Connected backwards:

  • No safe voltage level! (but not dangerous with vented caps)
     
  • Don't do it! (or.. do itttt 😈)

Connected correctly:

  • Safe as long as the applied voltage is less than the voltage rating
     
  • All our caps are rated at least 10V!
  • what is the recycling story for Tantalum?
     
  • what does the voltage number on the cap mean?

  • wait why do potentiometers have 3 legs?

Why do variable resistors have three legs?

Kirchoff's law

😱 math 😱

  • how tf do breadboards work

BC337 NPN Amplifier Transistor

  • We are going to use it really  wrong

Capacitor!

reversible!

usually really small
