But when the inducing charge is moved away, the charge is released and spreads throughout the electroscope terminal to the leaves, so the gold leaves move apart again. The sign of the charge left on the electroscope after grounding is always opposite in sign to the external inducing charge. [5] The two rules of induction are: [5] [6]
Besides sparkling water drinks, the company also produces ready-to-drink teas called Tejava in Bakersfield, California. [1] [2] In 1990 Crystal Geyser was acquired by Otsuka Pharmaceutical's parent company Otsuka Holdings Co. Ltd. [3] In 2014, the company had plans to bottle water from an aquifer in Mount Shasta, California, but many local residents criticized the plan.
The charge remains until it can move away by an electric current or electrical discharge. The word "static" is used to differentiate it from current electricity, where an electric charge flows through an electrical conductor. [1] A static electric charge can be created whenever two surfaces contact and/or slide against each other and then separate.

z j = number of charges of the j th ion; e = the elementary charge, 1.6022 × 10 −19 C; 4πε 0 = 1.112 × 10 −10 C 2 /(J⋅m); ε 0 is the permittivity of free space. If the distances r ij are normalized to the nearest neighbor distance r 0, the potential may be written
The only charges inside S are the charge Q on the object C, and the induced charge Q induced on the inside surface of the metal. Since the sum of these two charges is zero, the induced charge on the inside surface of the shell must have an equal but opposite value to the charge on C: Q induced = − Q .
Charge quantization is the principle that the charge of any object is an integer multiple of the elementary charge. Thus, an object's charge can be exactly 0 e, or exactly 1 e, −1 e, 2 e, etc., but not 1 / 2 e, or −3.8 e, etc. (There may be exceptions to this statement, depending on how "object" is defined; see below.)
In a macroscopic view, for charges on a segment of the loop, v consists of two components in average; one is the velocity of the charge along the segment v t, and the other is the velocity of the segment v l (the loop is deformed or moved).
