What is the Relationship between resistance and inductance in a RL circuit?
What is the Relationship between resistance and inductance in a RL circuit?
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.
What is the relationship between Power Ampere and resistance?
power=i square*resistance or power=v suare/resistance
The relationship between resistance and conductors is?
ALL resistance are conductors. just the magnitude value changes
What relationship does Ohm's law express?
Ohm's law gives the relationship between current, voltage, and resistance. The law states that I=V/R, where I is current, V is voltage, and R is resistance. Source: university digital fundamentals

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.
What is the mathematical relationship between resistance and conductance?
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)
What is the relationship between Power Ampere and resistance?
power=i square*resistance or power=v suare/resistance
What is the relationship between resistivity and circumference?
The relationship between resistivity and circumference is inverse.The resistance of a substance decreases as the surface area of that substance increases. The greater circumference presents a greater conduction surface.AnswerThe original answer describes resistance, NOT resistivity. Additionally, it is incorrect because resistance is inversely-proportional to cross-sectional area NOT circumference!There is NO relationship between resistivity and the circumference of a material. Resisitivity is a constant at any given temperature and is completely unaffected by the dimensions of a material.
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 the relationship between temperature and viscosity?
There is an inverse relationship between temperature and viscosity. That is, as the temperature increases, the viscosity decreases (the fluidity increases. However, the exact nature of the relationship is far from straightforward.
What is the relationship between elevations and climate?
The relationship between elevation and climate has to do with temperature. The higher up the elevation is the colder the temperature is.
What is the relationship between ohms resistance and amps for current?
The relationship is expressed by Ohm's Law: V=IR (voltage = current times resistance).
The relationship between resistance and conductors is?
ALL resistance are conductors. just the magnitude value changes
Is the relationship linear between density and temperature?
The relationship between density and temperature is linear. In a thermal expansion, density will decrease and temperature increases and vice versa.
