Electrical resistance and conductance The resistance (R) of an object is defined as the ratio of voltage across it (V) to current through it (I), while the conductance (G) is the inverse: R = V I, G = I V = 1 R {\displaystyle R={V \over I},\qquad G={I \over V}={\frac {1}{R}}} For a wide variety of materials and conditions, V and I are directly proportional to each other, and therefore R ...

resistance plasmid The definition of a resistance plasmid is a small element outside the chromosome that carries DNA information that fights against antibiotic drugs. An example of a resistance plasmid is pBR322 which carries the genes for tetracycline and ampicillin resistance. any of a group of bacterial plasmids carrying genetic information that provide resistance to antibiotic drugs: some resistance plasmids are able to transfer themselves, and hence resistance, during conjugation.

- Asked by: Venudhar. Resistance is a concept used for DC (direct currents) whereas impedance is the AC (alternating current) equivalent. Resistance is due to electrons in a conductor colliding with the ionic lattice of the conductor meaning that electrical energy is converted into heat.

resistance and ohm law Every material has an electrical resistance and it is the reason that the conductor give out heat when the current passes through it. Resistance is a measure of how much an object opposes the passage of electrons.The unit of electrical resistance is the ohm and it is represented by ω. Every material has Resistance. Copper has a low resistance and wood has a high resistance.esistance is a measure of how much an object opposes the passage of electrons. The unit of electrical resistance is the ohm and it is represented by ω. Every material has Resistance. Copper has a low resistance and wood has a high resistance.

Resistance An electron traveling through the wires and loads of the external circuit encounters resistance. Resistance is the hindrance to the flow of charge. For an electron, the journey from terminal to terminal is not a direct route. Rather, it is a zigzag path that results from countless collisions with fixed atoms within the conducting material. The electrons encounter resistance - a hindrance to their movement.

- You can think of resistance as being like a water pipe. A long, thin pipe makes it difficult for water to flow whereas a short, fat pipe makes it easy. The short, fat pipe has a smaller resistance and, for the same pressure, lets a bigger current flow through it.ou can think of resistance as being like a water pipe.

Rebellion Rebellion, uprising, or insurrection is a refusal of obedience or order. It refers to the open resistance against the orders of an established authority. The term comes from the Latin verb rebellō, I renew war (from re- (again) + bellō (I wage war/I revolt). The rebel is the individual that partakes in rebellion or rebellious activities, particularly when armed. Thus, the term rebellion also refers to the ensemble of rebels in a state of revolt. A rebellion originates from a ...

- The electrical resistance of a circuit component or device is defined as the ratio of the voltage applied to the electric current whichflows through it:Whether or not a material obeys Ohm's law, its resistance can be described in terms of its bulk resistivity.he electrical resistance of a wire would be expected to be greater for a longer wire, less for a wire of larger cross sectional area, and would be expected to depend upon the material out of which the wire is made.

- In this way, the enslaved often negotiated the basic terms of their daily routines. Of course, masters also stood to benefit from these negotiations, as contented slaves worked harder, increasing output and efficiency. Another common form of slave resistance was theft. Slaves pilfered fruits, vegetables, livestock, tobacco, liquor, and money from their masters.

Ohm (unit) By definition from Ohm's Law, a device has a resistance of one ohm if a voltage of one volt causes a current of one ampere to flow (R = V/I). Alternatively and equivalently, a device that dissipates one watt of power with one ampere of current flowing through it has a resistance of one ohm (R = P / I 2).

resistance and ohm law For example, a metre of copper has a resistance of only 1 Ohm but a metre of wood has a resistance of 10000000 ohm. We need resistance to reduce the flow of electrons through a circuit, so we can build resistors to behave as Electrical resistance. On the right, a resistor used in the electronic industry.

Resistance Mathematical Nature of Resistance. Resistance is a numerical quantity that can be measured and expressed mathematically. The standard metric unit for resistance is the ohm, represented by the Greek letter omega - . An electrical device having a resistance of 5 ohms would be represented as R = 5.

- Resistance refers to the property of a substance that impedes the flow of electric current. Some substances resist current flow more than others. If a substance offers very high resistance to current flow it is called an insulator. If its resistance to current flow is very low, it is called a conductor. Resistivity refers to the ability of substances to resist current flow. Good conductors have low resistivity and insulators have high resistivity.
