1. The problem statement, all variables and given/known data The coaxial cable from a television or other device has an inner conductor with diameter of 1 mm and the shield of diameter 5 mm. Assume a plausible value for the dielectric constant (3 ≤ κ ≤ 5) of the dielectric separating the two conductors and calculate the capacitance per unit length of the cable. 2. Relevant equations ? 3. The attempt at a solution I am really unsure of how to even start this problem. The answer they are looking for is a range ____ nF/m <= C/L <= _____ nF/m. Thanks in advance!
