What is the mathematical relationship between resistance and conductance?

∙ 11y ago
The relationship between resistance and temperature is determined by a material's temperature coefficient of resistance (symbol, the Greek letter 'alpha'). In general, pure metal conductors are said to have a positive temperature coefficient of resistance, which means that their resistance increases with increase in temperature; in general, insulators have a negative temperature of resistance, which means their resistance decreases with an increase in temperature. Carbon, a conductor, also has a negative temperature coefficient of resistance. This negative temperature coefficient of resistance explains why insulators fail at higher temperatures.
This topic is relatively complicated, so just one example will be given. Assuming we know the resistance (R0) of a material at 0oC , then we can find its resistance (Rx) at another temperature (Tx), using the following equation:
Rx = R0 (1 + alpha Tx)

∙ 11y agoI could be wrong but I believe you just one over it.. ie for say 10 ohms just do 1/10 to get conductance... not 100%exactly sure though
AnswerOne's the reciprocal of the other. Resistance is measured in ohms, while conductance is measured in siemens:
resistance = 1/(conductance)

What is shunt conductance?
A low-resistance connection between two points in an electric circuit that forms an alternative path for a portion of the current. Also called bypass. Conductance of a shunt is high as the resistance is low.
Relationship between resistance and capacitive reactance?
There is no physical relationship between resistance and capacitive reactance. But if someone tells you that the impedance of something: Z = 3 -4j, the real resistance is 3 and the reactive capacitance is -4.
What is transconductance?
Conductance is the reciprocal of resistance. If it is taken between one output parameter and one input parameter, then it is called transconductance i. e. the ratio of output current to the input voltage.It is given by gm= Iout/Vin
What is ohm's law expressed as a formula?
Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points, and inversely proportional to the resistance between them
What is the relationship between current and resistance?
They are proportional to each other with a constant of 1/V, by rearrangment of the formula V = IR.
What is the relation between hardness and conductivity?
Resistivity R is the inverse of conductivity G, R=1/G.
What is shunt conductance?
A low-resistance connection between two points in an electric circuit that forms an alternative path for a portion of the current. Also called bypass. Conductance of a shunt is high as the resistance is low.
What is the mathematical relationship between current voltage and resistance?
Voltage is the product of current times resistance, V=IR, I is Current and R is resistance. ANSWER: It is a simple ratio of 1:1:1
Relationship between conductance and viscous flow?
viscosity is inversily change with the conductivity
What is the difference between ohms and mohms?
ohms is the SI unit of resistance MHO (siemens) is the SI unit of reciprocal of resistance ie conductance
What is the mathematical relationship between heat dissipation and applied voltage?
Heat dissipation = (applied voltage)2 / total effective resistance of the circuit
What are mathematical relationship between resistance and specificconductivity constant?
Cell constant(C) = Resistance(R) X Specific Conductivity(K)
What is the Relationship between resistance and inductance in a RL circuit?
What is the Relationship between resistance and inductance in a RL circuit?
Difference between semen and mho which are the units of conductance?
The correct spelling is siemens, and it is the SI unit for conductance -the reciprocal of resistance. The mho is simply an obsolete unit for the same thing, and is numerically equal to the siemens.
What is the relationship between air resistance and movement?
air resistance is cooler
What is the relationship between resistance and capacitance in a clc circuit?
The relationship between resistance and capacitance in a clc circuit is the capacitive reactance given by XC.

the relationship between the LM, EM, SEM is the limit of resolution
