negative charges

The flow of current in a semiconductor can be formed by a flow of negative charges, as in the case of conductors.

If the amount of positive and negative charges is varied, the electron stream can be made to bend up or down in varying amounts.

When the trapped electrons are far apart, they do not interact strongly, and so behave somewhat like an array of isolated negative charges.

Vast numbers of positive charges collect at the bottom of the cloud. (2) Negative charges collect at the top of the cloud.

Those instituitions attract tourists by no or negative charges and then they gain their revenue by means of forced shopping.

The normal atom has an exactly equal number of positive and negative charges, so that the atom as a whole is neutral.

Ultracapacitors store electricity by physically separating positive and negative charges.

The positive and negative charges are then separated by updrafts and gravity, producing the electric field.

The other side of the hairpin carries a collection of negative charges, so that the whole caboodle is electrically neutral.

Friction can also separate positive and negative charges and generate strong static electric fields.

What is important to remember is that the formulas represent neutral compounds where the positive and negative charges add to zero.

Cells are covered in negative charges, so all you have to do is make the molecules you want to stick to them positively charged.

Two negative charges repel each other , and so do two positive charges .

HBPNis monomolecular dispersion in DMF, insoluble in water, but can be dissolved and bears negative charges on surface in alkaline solution;

Distribution of positive and negative charges inside a cumulonimbus cloud

In low and middling dosage of NDQ group, the negative charges of endothelial cell increased obviously (P05), compared to the controls;
