Airport runway lighting circuits avoid this problem by using constant current power supplies to supply the series circuit. Impedance and capacitance What if a series circuit consists of elements other ...

The fundamental circuit shown in Figure 1 generates timing for a two-phase stepper motor from an oscillator, as well as a direction (forward or reverse) signal. Figure ...

GFCI basics. Before we get into GFCI requirements, let's address two basic points. First, GFCIs do work on 2-wire circuits. A GFCI works by measuring the current on the ungrounded conductor and ...

AutomationDirect announces the release of a new White Paper, “Basic Pneumatic Circuits”, which discusses common pneumatic circuits that can be used alone or as building blocks in larger pneumatics ...

Researchers in Italy have created the first integrated circuit to combine two transistors made from the “wonder material” graphene. By adapting a technique used to fabricate silicon transistors the ...
