eddy currents are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to faraday’s law of induction. eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field. like lenz’s law, there are lots of...
The advantage of Optional Property is that it can clearly see which properties are there and prevent the passing of properties that do not belong to the interface. interface SquareConfig { color?: string; width?: number; } function createSquare(config: SquareConfig): {color: string; area: nu...

There are eight magical constants that change depending on where they are used. __LINE__: The current line number of the file. __FILE__: The full path and filename of the file. If used inside an include, the name of the included file is returned. Since PHP 4.0.2, __FILE__ ...
The Boltzmann constant, constant k or kB, is a proportionality factor named after the Austrian physicist Ludwig Boltzmann. He was considered the father of Modern Atomic Theory and also a statistical mechanics pioneer. One of the most important fundamental constants, this factor relates to temperature...
named after german physicist wilhelm weber. magnetic flux can be measured with a magnetometer. suppose a probe of the magnetometer is moved around an area of 0.6 m 2 near a large sheet of magnetic material and indicates a constant reading of 5 mt. then the magnetic flux through that area ...
so I thought. The RIAA equalisation curve needs three time constants, of 75µs, 318µs and 3180µs. I found pairs of resistors and capacitors that gave the same time constants as R1C1 and R2C2 even if their values weren’t what the original design specified. Here’s a circuit di...

It marks a function (member or non-member) as the function that can be evaluated at compile time if compile time constants are passed as their arguments. For example you can write this. constexpr int func_constexpr(int X, int Y) { return(X*Y); } int func(int X, int Y) { ...
