[Elecraft] Capacitors...simple yet complex question

I believe the difference in size is due to voltage ratings.
Small caps usually have a low voltage rating.  High voltage
caps are much larger.

Subject: [Elecraft] Capacitors...simple yet complex question

Kind Listees,

I have a question about capacitors.  When working on two power supplies 
recently, I came across two types of capacitors.  One type are the regular 
axial or radial Electrotic Caps that are, for example, 4700uF 
Capacitors.  Then, there are the Computer grade monster cans that are in 
Astron supplies.  Same capacitance value, but always much larger in 
physical size.  I know there are differences between the two in how they 
are constructed, but my question is do the differences make one or the 
other better?

Thanks.
