Dear mentors
I have a primary battery like this :
Car
12 volts
50 AH
450 A.
when I used the small window motor single transistor circuuit (that was produced by renaissance and charge), I hooked everything up.
What I noticed is that the resistor (going to unique coil) got immediatly very, very hot (can't touch it with hands after 3 seconds or so).
The transistor does not seem damdaged at all. The soldering from that resistor to the board melted , freeing one of its legs.
This is just the context where I asked myself : In Peter Lindemann and Aaron Murakami beginner's handbook, there is no "specification" of the battery, so my question is :
what could cause this hot ? a bad wiring ? or the car battery, much too powerful ?
Thanks...
