This authoritative compilation of formulas and tables simplifies the design of inductors for electrical engineers. It features a single simple formula for virtually every type of inductor, together with tables from which essential numerical factors may be interpolated. Although compiled in the 1940s, before calculators and computers, this book provides fundamental equations that professionals and practitioners can use to produce algorithms for computer programs and spreadsheets.Starting with a survey of general principles, it explains circuits with straight filaments; parallel elements of equal length; mutual inductance of unequal parallel filaments and filaments inclined at an angle to each other; and inductance of single-layer coils on rectangular winding forms. Additional topics include the mutual inductance of coaxial circular filaments and of coaxial circular coils; self-inductance of circular coils of rectangular cross section; mutual inductance of solenoid and a coaxial circular filament and coaxial single-layer coils; single-layer coils on cylindrical winding forms; and special types of single-layer coil. An esteemed reference, this volume belongs in the library of every electrical engineer.

Cat playground
Color: Black, Size: 35 Inch, Style: 3 Pack, Color: Black, Size: 35 Inch, Style: 3 Pack
Easy to install. Sturdy enough for 2 large rambunctious kitties to play on and look very nice. I was working on a vertical play space for the cats and since these come in many sizes it worked great. I did add grip tape to some.

Not the best quality
Color: Rustic Brown, Size: 35 Inch, Style: 2 Pack, Color: Rustic Brown, Size: 35 Inch, Style: 2 Pack
The shelving unit was not as I had expected. It arrived damaged. The damage is on the under side though. They are hollow and not hardwood as I had expected. Save your money if you want something of good quality. These are like 3 pieces of pressed wood glued together. They are space saving and look great in my space. The mounting hardware it comes with was plenty enough to hang these but make sure you hang them in the studs if at all possible. Assembly was simple. It does come with a micro level. Which a kid or pet could accidentally swallow. It’s like pill capsule sized so just be careful when opening the package.

Loving these
Color: Wooden Black
Two (Med and Large) will safely hold a larger electric power strip. The Small is on my desk holding odd items and bits that should be stored upright. They're so simple to use too! I love the colored Velcro strips that come with them and the plastic cable guides. I honestly didn't know they were included so that was a BONUS! It definitely helped sort my cables and power cords for my work station as well as my crafting station. Keeping them safely out of the way means my robot vacuum can run without any complications. The wood tops actually blend with the floors making them less visible. If I needed more I would certainly get more! I may buy more for gifting.

No More Messy Looking Cords Everywhere
Color: Wooden Black
These are such a great find! My office, bedroom and living room look so much cleaner now! The sizes were just right to meet our needs. The colors matched our decor and the cords no longer stick out like a sore thumb. It was easy to get the power strip and the cords organized inside the boxes and using these is just the perfect solution to a messy problem. Highly recommended!

Hides the cords well
Color: Wooden Black
Very subtle and hides the cords and surge protector well. They look appealing and blend in with other items well allowing them to not stand out. I wish the lid snapped on, though. Depending on the cords, it sometimes sticks up. But is an easy fix.
