The capacitance of a parallel plate capacitor when the plates are separated by air or free space. A parallel plate capacitor with a dielectric between its plates has a capacitance that is sensitive to the dielectric constant of the material. The maximum electric field strength when an insulating material break down is called dielectric strength.

Large molecules such as proteins, nucleic acids, and so on—so important to life—are usually electrically charged. DNA itself is highly charged; it is the electrostatic force that not only holds the molecule together but gives the molecule structure and strength.

It states that valence electrons will assume an electron-pair geometry that minimizes repulsions between areas of high electron density (bonds and/or lone pairs). Molecular structure, which refers only to the placement of atoms in a molecule and not the electrons, is equivalent to electron-pair geometry only when there are no lone electron pairs around the central atom.

These microtubules are hollow tubes composed of proteins that guide the movement of chromosomes when cells divide, the motion of other organisms within the cell, and provide mechanisms for motion of some cells (as motors).

(b) The dielectric reduces the electric field strength inside the capacitor, resulting in a smaller voltage between the plates for the same charge.
