Georg Simon Ohm 1787 - 1854
Georg Simon Ohm discovered how electromotive force works in an electrical circuit, including the relationship that resistance and current play within the circuit.
It was Georg Simon Ohm who defined the fundamental laws of current, resistance and voltage in an electrical circuit by using a basic formula:
I = E/R (This can also be transposed and rewritten): E = I x R (and also) R = E/I
Ohm's Law is one of the most important formulas in electrical theory.

How much is 1 megohm?
1,000,000 ohm
Is 2000k mean two thousand kilo ohms?
It just means 2,000,000.
What are the applications of decade resistance box?
A decade resistance box is piece of laboratory equipment that allows the user to dial in a precise amount of electrical resistance to be inserted into a circuit. For example, it might have a dial for 100s of Ohms, 10s of Ohms, and 1s of Ohms, and allow the user to set any value from 999 Ohms to 0 Ohms in 1 ohm steps. While the use of this device has probably been largely superseded in laboratory use by more sophisticated equipment, it was used in the past in some or all of the following applications: Measurement of unknown resistances by the "bridge" method, Setting the current in a test circuit, Calibrating other lab equipment such as an Ohmmeter or Ammeter, Demonstrating Ohm's Law, and so on.
What was luigi galvani's contribution to electricity?
He found out that frogs hold a charge of 40 ohms
What is one unit of electricity?
ohms
What limits the slow of electricity?
Resistance measured in Ohms
What does 0 ohms indicate?
0 ohms on your ohm meter indicates an open circuit; no resistance to the flow of electricity.
What scientist was the unit of Ohms named after?
George Ohm
If you have flow of electricity which is 5 volts and 2.6k ohms what is the current?
I = V/R 5 volts / 2600 ohms = .00192 or round to .002.
What does R stand for in electricity?
Resistance in an electrical circuit or device measured in ohms.
How easy or difficult it is for electricity to flow through a material measured in ohms?
resistance
What is the full form of OHMS?
A measurement of electricity. Discovered by George Ohm. Ohm being his last name. Not an abbreviation. A measurement of electrical current resistance based per 1 amp of current flow.
Who discover the ohms law?
George Ohm, a German physicist.
How does current electricity behave?
In a very predictable way. It follows Ohms law. Electrons do not flow instead they transfer their charge down a conductor to where they do work. Usually heating or lighting. They can excite a magnetic field and make a motor go. As a magnetic field is crossed by a conductor a current is generated.
How do electricians measure electricity?
Volts, amperes, watts and ohms. pressure (or force), current, energy, and resistance.
