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.
May 30, 2024 · Resistance, in electricity, property of an electric circuit or part of a circuit that transforms electric energy into heat energy in opposing electric current. Resistance involves collisions of the current-carrying charged particles with fixed particles that make up the structure of the conductors.
Put simply, resistance is a force that counteracts the flow of electricity. Resistance influences the flow of electricity. This page offers basic knowledge about resistance, along with a detailed explanation of topics such as calculation methods and resistors.
The meaning of RESISTANCE is an act or instance of resisting : opposition. How to use resistance in a sentence.
Definition of resistance noun in Oxford Advanced Learner's Dictionary. Meaning, pronunciation, picture, example sentences, grammar, usage notes, synonyms and more.
RESISTANCE meaning: 1 : refusal to accept something new or different often + from often + to; 2 : effort made to stop or to fight against someone or something
Electrical resistance is the hindrance to the flow of charge through an electric circuit. The amount of resistance in a wire depends upon the material the wire is made of, the length of the wire, and the cross-sectional area of the wire.
Resistance is the property of a material or component that opposes the flow of electric current through it. It is measured in Ohms and denoted by the symbol “Ω”. Resistance arises due to the interactions between electrons and the atoms or molecules that make up the material.
The resistance of a coaxial cable depends on its length, the inner and outer radii, and the resistivity of the material separating the two conductors. Since this resistance is not infinite, a small leakage current occurs between the two conductors.
Having more lamps in series means that the resistance of the circuit is more. Less current flows so the bulbs are dimmer. Resistance is measured in units called ohms, which is represented by...
Whether or not a material obeys Ohm's law, its resistance can be described in terms of its bulk resistivity. The resistivity, and thus the resistance, is temperature dependent. Over sizable ranges of temperature, this temperature dependence can be predicted from a temperature coefficient of resistance.
Jul 11, 2021 · A SIMPLE explanation of Electrical Resistance. Learn what Electrical Resistance is, the symbol and formula for resistance, and AC vs DC resistance. We also discuss heating, temperature and ...

Review the key terms, equations, and skills related to current, resistance, and resistivity, including how to find the current direction and what resistance depends on.
The SI unit of electrical resistance is the ohm ( Ω ), while electrical conductance is measured in siemens (S) (formerly called the 'mho' and then represented by ℧ ). The resistance of an object depends in large part on the material it is made of.
C2 [ U ] the act of fighting against something that is attacking you, or refusing to accept something. 抵抗;反抗;反對. resistance to disease 抗病. Government troops offered no resistance ( to the rebels ). 政府軍沒有（對叛軍）作出任何抵抗。. There's a lot of resistance (= opposition) to the idea of a united Europe ...
Electric resistivity is defined as the electrical resistance offered per unit length and unit cross-sectional area at a specific temperature and is denoted by ρ. Electrical resistance is also known as specific electrical resistance.
Resistance refers to a measure of the opposition to current flow in a particular electrical circuit. The electrical resistance of an object refers to the measure of its opposition to the flow of electric current. The inverse quantity refers to the electrical conductance.
For a given shape, the resistance depends on the material of which the object is composed. Different materials offer different resistance to the flow of charge. We define the resistivity \(\rho\) of a substance so that the resistance \(R\) of an object is directly proportional to \(\rho\).
Resistance is the physical property of a substance because of which it opposes the flow of current i.e. electrons. Resistivity is the physical property of a particular substance which is having particular dimensions.
Use resistivity to calculate the resistance of specified configurations of material. Use the thermal coefficient of resistivity to calculate the change of resistance with temperature. Material and Shape Dependence of Resistance. The resistance of an object depends on its shape and the material of which it is composed.
Bacteria are evolving resistance to antibiotics. He was famed for his stubborn resistance and his refusal to accept defeat. There has been strong resistance to the proposed tax increases. Following a determined resistance in the east, there was eventually a popular uprising in the capital.
