WHAT IS AN OP-AMP?:
http://talkingelectronics.com/project…

My components:

* Infineon MOSFET N-channel 200V 13.5A TO-220 – BUZ31L H (I will be using two of these in parallel)
* Vishay 534 Series Pot with 6.34mm shaft, 50K
* Vishay 534 Series Pot with 6.34mm shaft, 5K
* 1 x 10 k Ohm resistor
* 1 x 10 turn 10K trim pot
* Arcol HS50 Al house wirewound high power resistor,1R (1 ohm) 50W – HS50 1R J
* National Semiconductor Quad op amp,LM324N 1MHz DIP14
* 1uF Capacitor

* How does an N Channel logic level MOSFET work – gate voltage, variable resistance, heat dissipation.
* How does a LM324N Op Amp work – voltage follower, comparator, rail to rail, head room, feedback loop.
* What is the heat / power dissipation from a variable resistor?
