Coming from an IT background to an AM transmitter site might leave you with a world of questions. Mark Persons explains the ...

A series of resistors has been developed by EPCOS that are designed for applications as charging resistors for link-circuit capacitors in industrial power supplies, frequency converters and UPS ...

Our last go-round inside a DC circuit! We’ll encounter junctions, loops, and capacitors! What happens when there are MULTIPLE batteries, connected in ‘parallel’? And what happens when we add ...

The energy in that one capacitor is ½*C*V² = 0.5 * 1X10 -6 * 10² = 5X10 -5 joules = 50 µ-joules. The second capacitor has no charge and therefore has zero stored energy. This means that the two ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

In a classic parallel plate capacitor, the capacity goes up as the distance between the plates shrinks. In an electrolytic, one plate is a rolled up spiral. The other plate is conductive fluid.

Using voltage feedback from the capacitor bank being charged, a MOSFET-based current-control approach applies a stepped series of increased charging currents to limit inrush current.

UK based ARCOL Resistors announces the availability of its RW Discharge Resistor.

Resistors in parallel Current When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor.
