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 ...

A quartz crystal's case will be stamped with the devices' rated operating frequency, but that number is only an approximation to the real story which is that there is more than one crystal resonant ...

Even small objects, such as dust and leaves, can block sunlight from reaching solar cells, and understanding how the loss of incoming radiation affects power output is essential for optimizing ...

More often than not a question pops up in our forum about speaker impedance and the result of connecting multiple speakers to a single amplifier. Thus we have prepared this introductory tutorial to ...
