A review of the universal gravitational law and the size of the constant G. Coulomb's law was written and shown to be an inverse square relationship like Newton's gravitational equation. The equations are very much alike, Gravity being F=Gxm1m2/d squared and electrical force being F = k q1q2/d squared. The electrical force is millions of times stronger than the gravitational force.
The unit of charge is the Coulomb (C). 1C = 6.24 x10>18 electrons. The value of k and the value of a charge on an electron and/or proton was discussed, along with a problem involving the electrical force formula. Insulators and conductors was discussed in terms of electron roaming, along with methods of charging a static electrical object.
