Hi everyone, My question is about the origin of ohm's law, how it was discovered. Ohm's law is pretty simple and I don't have any problems using it. My real problem is understand how it was discovered. I was able to find a translated book of Georg Ohm ("The Galvanic Circuit Investigated Mathematically"), but this book makes no sense to me at all. I couldn't even find his famous equation in that book. I know that by the 1800's they were able to measure current using tangent galvanometers and other instruments. I would like to know what experiments were conducted to conclude E = IR. Thanks.
