Bricks In The Wall
a: Electric charge ~
b: brick wall
What: "Millikan's experiment showed that electrical charge is quantized, meaning that charge exists only in little "pieces" of definite size. The size of any electric charge is an integer multiple of this smallest possible "elementary charge." Consider the following analogy; an electric charge is like a brick wall - the smallest possible size for a wall is one brick, a single brick is like the elementary charge. Just as a wall can not exist that is smaller than one brick, an electric charge can not exist that is smaller than the "elementary charge." Any large brick wall is made up of an integer number of bricks, just as any large electric charge is made up of an integer number of elementary charges."
