I'm wondering why coaxial cable would be characterized by conductance per unit length but not resistace per unit length
Thanks for all yall's help, again

- Conductance Resistance
In summary, conductance and resistance are opposite properties of a material, with conductance measuring how easily electricity can flow through a material and resistance measuring how much it impedes the flow. They are inversely related, with high conductance corresponding to low resistance, and are measured in siemens (S) and ohms (Ω), respectively. In electrical circuits, they determine the amount of current and voltage needed for efficient and effective functioning. These properties can be measured using specialized instruments such as ohmmeters and multimeters.

I'm not sure why this would be a problem, since the resistance is the reciprocal of the conductance, and vice versa. So given one, you automatically have the other.

Same thing I was thinking
1. What is the difference between conductance and resistance?
Conductance and resistance are opposite properties of a material. Conductance refers to how easily electricity can flow through a material, while resistance refers to how much the material impedes the flow of electricity. In other words, conductance measures how conductive a material is, while resistance measures how resistive it is.
2. How are conductance and resistance related?
Conductance and resistance are inversely related - as one increases, the other decreases. This means that a material with high conductance will have low resistance, and vice versa. Mathematically, they are related by the equation G = 1/R, where G is conductance and R is resistance.
3. What units are used to measure conductance and resistance?
Conductance is measured in siemens (S), while resistance is measured in ohms (Ω). These units are related by the equation G = 1/R, so 1 S is equal to 1 (Ω)-1.
4. How do conductance and resistance affect electrical circuits?
Conductance and resistance play a crucial role in the behavior of electrical circuits. Conductance determines how much current can flow through a circuit, while resistance determines how much voltage is needed to push that current through. In general, lower resistance and higher conductance make for more efficient and effective circuits.
5. How can conductance and resistance be measured?
Conductance and resistance can be measured using specialized instruments called ohmmeters or multimeters. Ohmmeters measure resistance directly, while multimeters can measure both resistance and conductance. These measurements can help determine the properties of a material and how it will behave in an electrical circuit.
