Webb12 mars 2024 · Georg Ohm, in full Georg Simon Ohm, (born March 16, 1789, Erlangen, Bavaria [Germany]—died July 6, 1854, Munich), German physicist who discovered the law, named after him, which states that … Webb9 feb. 2024 · First we must compute the current through each bulb, using Ohm’s law: Substituting V ¼ 120 V and R1 ¼ 240 V into V = I x R, we obtain I 1 = 0.5 A. For R 2 = 480 V, we get I 2 = 0.25 A. Now we can use these values for I and R in the power formula, P = I 2 x R, which yields P 1 = (0.5 A) 2 x 240 V = 60 W and P 2 = (0.25 A) 2 x 480 V = 30 W.

Webb16 jan. 2024 · Ohm’s law: Ohm’s law is one of the fundamental laws in physics that governs electrical and electronic circuits. Ohm’s law is known to be the relation between voltage and current. The law states that the voltage in a conductor is directly proportional to the current through it. WebbWhen Ohm published his formula in 1827, his key finding was that the amount of electric current flowing through a conductor is directly proportional to the voltage imposed on it. …
