Ohm's law tells us that the current flowing through a resistor is equal to the Voltage across the resistor divided by the resistance. Georg Ohm invented the basic electrical law: Resistance (measured in ohms) = voltage (measured in volts) divided by current (measured in amps) which was later given his name: Ohm's Law.
Ohm's Law can also be used to find voltage and current when it is expressed as: Volts = amps x resistance and Amps = volts / resistance. The ohm is an international standard unit of measure.
Ohm's law, that electric current is proportional to a potential difference, was first discovered by Henry Cavendish, but Cavendish did not publish his electrical discoveries in his lifetime and they did not become known until 1879, long after Ohm had independently made the discovery and published himself. Ohm experimented with optics, acoustics, and the electrical conductivity of liquids, though he didn't achieve any real progress…
If the loads are wired in series, add the three values to get the total R.
He also created a formula that would calculate the relationships: V = I x R I = V/R R = V/I Ohm's Law is Voltage = Current x Resistance.
If you know any two of the parameters you can calculate the other.
Ohm's law states that the current through a conductor is directly proportional to the voltage across the conductor and inversely proportional to the resistance of that conductor.
- [Instructor] What we will introduce ourselves to in this video is the notion of electric circuits and Ohm's law, which you can view as the most fundamental law or the most basic law or simplest law when we are dealing with circuits.
Ohm's Law does NOT describe the relationship between potential difference, current, and… Ohm's Law simply tells us that, for ohmic or linear materials, the ratio of voltage to current is a constant.
The equation you are, presumably, looking for is derived from the definition of the ohm, not from Ohm's Law, and that is resistance is voltage divided by current.
