ELECTRICAL ENCYCLOPEDIA

Discovery of Ohm's Law projects.sd3.k12.nf.ca   Ohm’s law is the mathematical relationship among electric current, resistance and voltage. The principle is named after the German scientist Georg Simon Ohm. Ohm demonstrated that there are no "perfect" electrical conductors through a series of experiments in 1825. Every conductor he tested offered some level of resistance. These experiments led to Ohm’s law. Ohm’s law of 1826 states that if the given temperature remains constant, the current flowing through certain conductors is proportional to the potential difference (voltage) across it. In other words, current equals voltage divided by resistance. How Voltage,Current Resistance relates www.allaboutcircuits.com/   An electric circuit is formed when a conductive path is created to allow free electrons to continuously move. This continuous movement of free electrons through the conductors of a circuit is called a current, and it is often referred to in terms of "f...
