Conductance is a measure of an object's ability to conduct electricity. It is the reciprocal of resistance and is measured in siemens (S).
Conductance and conductivity are closely related. Conductivity is a material's ability to conduct electricity, while conductance is the measure of an object's ability to conduct electricity. Conductivity is measured in siemens per meter (S/m) and is equal to the product of conductance and the cross-sectional area of the object divided by its length.
Conductance and resistance are both measures of an object's ability to conduct electricity. The main difference is that conductance measures how easily electricity can flow through an object, while resistance measures how much an object impedes the flow of electricity. Conductance is the reciprocal of resistance.
Conductance is calculated by dividing the current (I) flowing through an object by the potential difference (V) across the object. It is represented by the equation G = I/V. Conductance can also be calculated by taking the reciprocal of the resistance (R).
Several factors can affect conductance, including the material of the object, its length, cross-sectional area, and temperature. Materials with high conductivity, such as metals, have a higher conductance than materials with low conductivity, such as rubber. Longer objects have higher resistance and lower conductance, while objects with larger cross-sectional areas have lower resistance and higher conductance. In general, higher temperatures decrease the conductance of a material.
