Sometimes, it's the little things that are just so darn handy to have around. I'm often confronted with having to choose a parallel pair of resistors to get as close as possible to some non-standard ...

Previous tutorials have described that resistors may either be connected as a series circuit or a parallel circuit where the currents and voltages are obtained using Ohm’s Law. To produce more complex ...

You can avoid solving simultaneous equations in multiple unknowns by identifying series and parallel combinations of resistors.

If you work on RF circuits–even if you aren’t a ham radio operator–you ought to have a dummy load. A dummy load is a non-radiative “antenna” with known impedance that you can use to test your RF ...
