Georg Simon Ohm was a German schoolmaster who discovered that for certain conductors, the ratio of voltage to current was constant for variations in voltage.
He thought that this applied to all conductors, but this is not the case. In fact, Ohm's Law applies to very few conductors and, then, only under very specific conditions.
What else can I help you with?
Who discover the ohms law?
George Ohm, a German physicist.
What did ohm discover about these three factors?
Ohm discovered that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor. This relationship is known as Ohm's Law.
What are the Contribution and discovery of george Simon ohm in electricity?
By discover of magnetic field hoped we helped
What relationships did ohm discover between the three factors?
Ohm detected the following one V = R * I Here V is the potential difference across a conductor. R- resistance of the conductor and I is the current that flow through the conductor.
In what way does georg Simon ohm discovered ohms?
Ohm tested different sized wires in circuits to see what effect the resistance of the wire had on the current. Based on the amount of the output energy there was, he could prove the relationship between resistance, current, and voltage.AnswerGeorg Simon Ohm didn't 'discover' the ohm (unit of measurement); it was named in his honour some time after his death. He is credited with coining the word 'resistance', which corresponds to the ratio of voltage to current. Remember, that in Ohm's day, there were no amperes or volts or ohms -these were all standardised after his death.
What is a unit used to measure resistance?
The " Ohm " is. 1 ohm is the resistance across which 1 volt of EMF appears when the current through it is 1 Ampere.
Who discover current?
The mathematical equation describing the relationship between electric current, voltage, and resistance was discovered by George Ohm in the 1820s. Ohm's Law states that current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R), expressed as I = V/R.

Which is bigger resistance 20 ohm or 200 ohm?

What relation dod goere ohm discover between voltage current and resistance?
Ohm discovered that, for some conductors, the current flowing through the conductor is directly proportional to the potential difference across them. This does not apply to allconductors -in fact, it applies to very few. Ohm's Lawstates that 'the current flowing in a wire is directly proportional to the potential difference across that wire, providing its temperature (as well as other factors) remains constant'.Ohm's Law makes no mention of resistance. The equation, R= V/I is derived from the definition of the ohm, and not from Ohm's Law, and applies whether Ohm's Law is followed or not. For Ohm's Law to apply, there must be a linear relationship between the ratio of V:I . Those materials that obey this rule are called 'ohmic' or 'linear', while those that do not obey this rule are called 'non-ohmic' or 'non-linear' -most materials are 'non-ohmic'.
