The lead-in wires from a television antenna are often constructed in the form of two parallel wires (Fig. P32.75)
(a) Why does this configuration of conductors have an inductance?
(b) What constitutes the flux loop for this configuration?
(c) Ignoring any magnetic flux inside the wires, show that the inductance of a length x of this type of lead-in is where a is the radius of the wires and w is their center-to center separation. |
