Question

A capacitor is constructed of two aluminum plate separated by a dielectric. the capacitance is measured to be 268.00 uf. without changing the dimensions of the plates, they are brought closer together so that the distance between the two plates is 1/2 of the original distance.
What is the new capacitance (in μF)?

Answer 1

Twice
see http://hyperphysics.phy-astr.gsu.edu/hbase/electric/pplate.html

same E, less distance

Answer 2

typo - excuse me, same V, less distance, so greater E

Answer 3

@Damon, can you explain me what you wrote

Answer 4

I don't understand
