What is a DRY Electrolytic?????

while we are on the subject of caps. here's a question i have never really been sure of, when you take a cap. wired in a parallel the lets say 22 mfd 450 v with another that is equil in value, it becomes 44 mfd what then is the voltage rating become together is it now 900 v or 225 v or remain 450 v. could it now be used in a circuit requiring a 800 volt 44 mfd cap ,or stay at 450 v making it a 44 mfd 450 cap. or what is the voltage rating become of two caps in a serise 22 mfd + 22mfd = 11 mfd does the total voltage together drop along with mfd value , or increase because there are two in a series . this is why i have never used caps. in this way unless the voltage needs were way below any concern.
