The electrical resistance of an electrical conductor is the opposition to the passage of an electric current through that conductor. Define specific resistance. Q. Define temperature coefficient of resistance. Q. Define electric resistance of a conductor. Q. Define resistance and resistivity. Give the relation between them.
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. The SI unit of electrical resistivity is Ωm. Following is the formula of electrical resistivity: Where,
resistance to sth The government faces resistance to the bill. There should be no resistance to the new management structure a force which acts to stop the progress of something or make it slower :
A measure of the degree to which a substance impedes the flow of electric current induced by a voltage. Resistance is measured in ohms. Good conductors, such as copper, have low resistance. Good insulators, such as rubber, have high resistance. Resistance causes electrical energy to be dissipated as heat.
The meaning of RESISTANCE is an act or instance of resisting : opposition. How to use resistance in a sentence.
The electrical resistance in its purest form that opposes the current flow without any dependency on the frequency of the voltage supply is called resistance. While the impedance is the opposition to the current flow that is affected by the supply frequency.
The ability of a material or object to slow down the free flow of electrons of an electric current. Good conductors, such as copper, have low resistance. Good insulators, such as rubber, have high resistance. Resistance results in a change of electric energy into heat.
[uncountable, singular] dislike of or opposition to a plan, an idea, etc.; refusal to obey As with all new ideas, it met with resistance. resistance to somebody/something There has been a lot of resistance to this new law. Resistance to change has nearly destroyed the industry. Want to learn more?
The resistance of a conductor is directly proportional to the potential difference applied across the conductor and inversely proportional to the current flowing through the conductor. The SI unit of resistance is the ohm, which is derived from the Greek letter omega Ω. Define the term resistivity of a conductor. Give its SI unit.
Jun 20, 2024 · Resistance (also known as ohmic resistance or electrical 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). The larger resistance, the greater the barrier against the flow of current.
