Printed circuit boards (PCBs) are the essential building blocks behind almost all modern electronic devices. These components ...

Such a solver is working on a truly 3-dimensional description of the structure under observation. In order to solve a given structure, that structure needs to be 'meshed', which means it is divided ...

To understand a series circuit, visualize it. You can do that by making a drawing. Just draw a box, to start with. This box represents your circuit. Notice there is only one path: the perimeter of the ...

After the critical circuits, we like to examine the printed-circuit board (PCB) stackup. Like the schematic, board stackup decisions are often made prior to routing and placement, so this is a good ...

If the power source is a listed Class 2 transformer or listed Class 2 power supply — or it’s in listed equipment marked to identify the Class 2 power source — you’ve got a Class 2 circuit between the ...
