Question

ybarrap · Answer

Can you explain what you mean by "joining?" Do you mean "connecting?"

anonymous · Answer

Joining specifically means series and parallel combination.......
1.If two or more capacitors are connected in series, the overall effect is that of a single (equivalent) capacitor having the sum total of the plate spacings of the individual capacitors. 

2.If two or more capacitors are connected in parallel, the overall effect is that of a single equivalent capacitor having the sum total of the plate areas of the individual capacitors. 

Hope it helps!!
