What is a unit resistance?

The unit of the electrical resistance, measured with direct current, is the ohm (abbreviated Ω), named after the German physicist and mathematician Georg Simon Ohm (1789-1854). According to ohm’s law, the resistance R is the ratio of the voltage U across a conductor and the current I flowing through it: R = U / I.

What is resistance and unit of resistance?

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.

What is the SI unit of resistance answer?

SI unit of resistance is Ohm ( ‎Ω ). Resistance = Volt/ Ampere = ‎Ω; a circuits resistance is 1 Ohm when a potential difference of 1 volt is required to produce a current flow of 1 ampere.

What is SI unit of resistance and resistivity?

R = Resistance, L= Length, A = Cross-sectional area. 5. SI Units. The SI unit of resistance is Ohms. The SI unit of resistivity is Ohms-meter.

What is the unit resistance?

Who was the man who discovered electrical resistance?

Georg Simon Ohm. – a summary of the life of Georg Simon Ohm, the man who discovered electrical resistance and gave his name to Ohm’s Law. Ohm is a name which is synonymous with the most basic electrical and electronic theory.

Who is the discoverer of the law of resistivity?

Resistivity. The German physicist Georg Simon Ohm discovered the basic law of electric conduction, which is now called Ohm’s law. His law relates the voltage ( V, measured in volts), the current ( I, in amperes), and the resistance ( R, in ohms) according to the formula V … Resistivity, commonly symbolized by the Greek letter rho, ρ,…

Who was the inventor of the unit of measurement?

(1818–1889) The unit that measures work, or energy (a force acting over distance), honors the British physicist who established that all forms of energy are equivalent. He also developed thermodynamics, along with Lord Kelvin.
