The possibility of creating a frequency-tunable function generator with rectangular and triangular pulses of constant amplitude and electronic synchronous control of equivalent capacitances in the ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

Devices that plug into an AC mains outlet need protection from EMI. A Pi filter, as shown in Figure 1, is often used for this application. Safety standards exist to protect people and equipment should ...

This solar clock was built using a lot of salvaged parts. We find it interesting that [Nereus] combined a ring of storage capacitors with a power cell (translated) to create a hybrid energy storage ...

Out of all of the fundamental passive electronic components, capacitors are arguably the most abundantly used. In fact, it is hard to find a circuit board that does not have a capacitor on it and a ...

The top image shows the construction of the ZnS/CuS anode and carbon fiber cathode used in the experiment. The bottom image illustrates the performance of the ZnS/CuS anode/cathode construction ...
