Excessive use of electricity and poor efficiencies are no longer acceptable. Eliminating poor power factor will result in increasing electrical efficiencies and will reduce the overall use of ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...

With their ability to resist changes in current, inductors are one of the basic but fundamental components used in electronics where current and voltage change with time. This tutorial provides an ...

TDK has created a SMD inductor particularly for the bias-tee (bias-T) circuits used to split RF signals and dc power from, or combine them onto, a single line. “The component achieves an inductance of ...

The motion of charged particles causes electrical effects, small shocks, lightning and sparks. Electrical fields cause forces to act on charged particles. How to affect electric current - OCR 21st ...
