This value is proportional to plate area and inversely proportional to distance in its namesake parallel-plate device, and its product with voltage is the charge.
For the characteristic impedance of a lossless transmission line, this value is multiplied by "j omega" in the denominator of the square root. For a circuit, the impedance is equal to the reciprocal of the complex unit times angular frequency times this value. This value is proportional to the reciprocal of the log of the ratio of the (*) shell diameters for a coaxial cable. This value is proportional to plate area and inversely proportional to distance in its namesake parallel-plate device, and its product with voltage is the charge. For 10 points, name this quantity that describes the ability of a namesake circuit element to store charge.
