It gives the force between two charges.[ATTACH=full]175066[/ATTACH]So if we place two spheres charged with 1 coulomb negative and positive each, 1 meter apart, the attraction force between them is about 9 Billion Newtons! (9,000,000,000 N!) That is enough force to lift 900,000 tons. 1 coulomb is not huge. By define of amps, a current flow of 1 ampere for 1 second gives 1 coulomb. A small pen torch (AA) battery has about 1500mAh, so about 5400 coulombs in it (1.5A x 3600 seconds).Let's imagine one sphere is attached to a massive piston weighing 1 ton (1000 kg). Other sphere is held fixed 1 meter away. Now you give 1 mili coulombs negative and positive to both spheres each. The piston gets a force of 9000 newtons, and from F= MA, is accelerated 9 ms-2, hits other charge and gets canceled. Then you charge them back with both positive at 1 mili coulombs, so the piston goes back. Remember. 1 pen torch battery has 5400 coulombs, so 5.4 million mili coulombs. Since 1 time takes 2x2=4 mili coulombs, one battery can do this 1.35 million times. Since a day has 86400 seconds, if it's done once per second, it can do this for more than 16 days or more than two weeks.You read that right! From this setup, a single pen torch battery can move a 1 ton (1000 kg) piston back and forth 1 meter (as in piston stroke), 1 time per second for two weeks. Just imagine how massive 1 ton piston is, and if it can move 1 meter back and forth every second for 2 weeks, how much energy that is! Easily like a big power plant like නොරොච්චෝලේ. This is obviously ridiculous, but Math checks out! Either coulomb's law is fake, or we can power sri lanka with a few pen torch batteries. If you can, prove me wrong.</blockquote>
