You can make all sorts of different types of inductors, but the most common type is cylindrical coil of wire---a solenoid. When current runs through the first loop, it creates a magnetic field that ...

The use of air-break disconnect switches to interrupt the capacitive currents associated with open‑ended bus runs and short lines is common practice. In most cases, the current magnitude is no more ...

Matt Cuhadar is a key member of the Ametherm team, Matt Cuhadar has provided support for the company's customers as an application and sales engineer for the last two years. He holds a B.Sc. in ...

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 ...

In the conventional dc-dc converter buck topology (Fig. 1), power from the input voltage source is transferred to the output filter by turning on the pass transistor. When the pass transistor is on, ...

Correctly installing capacitors at the terminals of your motors can lower reactive power requirements and increase system power factor. Induction motors are the primary source of rotary power in the ...

If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...
