In doing my brushing up on electronics, I am at the point of putting 
together a breadboard circuit (this is in a " do it yourself" course).  
A friend loaned me a scope, and I am supposed to check the action of the 
circuit, and see if it behaves the way the mathematics says it is 
supposed to behave.  .

Only thing is, I have read some postings recently where tantalum 
capacitors were exploding because of the wrong polarity, and I am 
feeling a little bit insecure in what I am doing.  :-(

I have an operational amplifier (op amp) breadboarded up, with +12 volts 
and -12 volts.  Each leg of the voltage has a 10 microfarad electrolytic 
capacitor going to ground.  On the +12 volts side, I have the minus side 
of the capacitor going toward ground.  On the -12 volts side, I have the 
plus side of the capacitor going to ground, since ground in this case is 
more positive than the -12 volts.

But I worry that I may not be understanding something here, although it 
seems right.  Lord knows I don't need any capacitors exploding in the 
bedroom!  I would be banished to the basement, at best.

Thanks,
Bill
