Where is the reference database and formulae available to calculate the lead inductance of copper strapping given the width and depth in inches and the length of the copper strap in feet? The interes

It depends on how close it is to ground. You have to estimate the characteristic impedance of the strap as if it were a microstrip-type transmission line, ignoring any dielectric material. Then the

It depends on how close it is to ground. In practical circumstances, doesn't the shape of the strap -- that is, how many bends, and how sharp -- have as much or more effect? I'm assuming that we're t

This is a non trivial calculation, for a variety of reasons. NBS Circular 74, published more than 50 years ago, will have some formulae. The "tome" in this field is a work by Grover... Some of it is
