\r\n Ohm's law, named after German physicist Georg Simon Ohm, is one of the fundamental principles of electricity.\r\n Ohm's law relates the voltage applied across a conducting material to the electric current flowing through it.\r\n Ohm, while experimenting with electrochemical cells, found that the electric current flowing through a conducting material is directly proportional to the voltage applied.\r\n Mathematically, Ohm's law can be expressed as:\r\n $$ I \\propto V $$\r\n Expressed as an equality (by introducing a proportionality constant \\(R\\)):\r\n $$ I = \\frac{V}{R}$$\r\n where \\(V\\) is the voltage loss across the conductor, \\(I \\) is the electric current through it. \\(R\\) is the ratio of voltage to current, and is known as the electric resistance of the conductor.\r\n For certain materials, this ratio \\(R\\) remains constant over a broad range of values of \\(V\\) and \\(R\\). Such conductors are known as Ohmic conductors.\n
\r\n\n Based on Ohm's law, the following conclusions can be deduced about electric circuits.\r\n
