ElectricalMath on Instagram: "Ohm’s law explained in one minute. When a voltage is applied across a conductor, the size of the current that flows through it depends on the resistance said conductor offers to the flow of electrons. Physically, this is due to collisions between the electrons and the atoms of the conductor. In 1826, a German scientist named Georg Ohm found experimentally that in metal conductors, current is directly proportional to voltage at a fixed temperature. This became known
