Vay Posted February 20, 2009 Posted February 20, 2009 I was reading the book "General Chemistry" by Linus Pauling and i stumbled upon a confusing part where it explains the IS units of coulomb. The book explained Coulomb; "The coulomb is one-ampere second, and the ampere is defined as the current in each of two infinitely long parallel wires 1 meter apart that causes an electromagnetic force of 2 x 10^-7 newton per meter of its length to act on each wire." as quoted from the book. This definition i did not just get from the book, i searched up online and the other sources also said infinitely long parallel lines. I am confused at the "infinitely" long parallel wire part. What is this infinitely long parallel wire? Are infinitely long parallel wires even possible?
