Elementary charge the difference between the particle "electron" and the unit of charge "electron" was still blurred. Later, the name "electron" was assigned to the particle and the unit of charge "e" lost its name. However, the unit of energy electronvolt reminds us that the elementary charge was once called "electron". The maximum capacity of each pixel in a charge-coupled device image sensor, known as the "well depth", is typically given in units of electrons, commonly around 10 per pixel. In high-energy physics (HEP) Lorentz–Heaviside units are used, and the charge unit is a dependent one, formula_1, so that = 0.30282212088 .
Charge conservation destroyed, equal numbers of positive and negative charges are destroyed. This property is supported without exception by all empirical observations so far. Although conservation of charge requires that the total quantity of charge in the universe is constant, it leaves open the question of what that quantity is. Most evidence indicates that the net charge in the universe is zero; that is, there are equal quantities of positive and negative charge. Charge conservation was first proposed by British scientist William Watson in 1746 and American statesman and scientist Benjamin Franklin in 1747, although the first convincing proof was given by
