A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.

There are times when one needs to take an digital signal and create the inverse of this signal. Doing this in discrete components can be challenging to fit into a small space. Lucky for us there are ...

If you have to sample just a few low-rate analog signals, or your PC's slots are all full or too outdated for the newer data-acquisition products, a simple interface may be all you need. You can build ...

A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types to more sophisticated ...
