    • Piezoelectric Transducer

      Piezoelectric Transducer

      A piezoelectric transducer is a device that converts electricity into mechanical forces or vibrations. Although piezoelectric transducers have other uses, ultrasonic devices require them. Piezoelectric transducers usually converts electricity into vibrations and vibrations into electricity, although this is not always the case. They rely on two phenomena known as “electrostriction” and “the piezoelectric effect.” How

    • TRIAC

      TRIAC

      A TRIAC is used in AC power control applications in order to switch high voltages over both parts of the AC waveform. As a result, TRIAC circuits are used in a number of applications that require power switching. The TRIAC was developed after the thyristor, which controls AC current over one half of the cycle.

    • What is a Clock Generator?

      What is a Clock Generator?

      A clock generator is a type of circuit that produces a continuous, synchronized electrical signal for timing purposes in a wide variety of devices. Because many high end electronic equipment require that electrical signals and mechanical devices work together in an efficient manner, clock generators are often a necessary component in many devices in order

    • Zener Diode

      Zener Diode

      A Zener diode transfers current forward and backward, while traditional diodes are only capable of transferring current forward. Many different electronic systems use Zener diodes to control their circuit’s voltage levels. While there are several ways of doing this, Zener diodes provide efficient voltage regulation without damaging the diode itself. How Zener Diodes Work For

    • What is an Isolation Transformer?

      What is an Isolation Transformer?

      An isolation transformer is made of two copper coils that are wound around each other and are each supplied by their own power source. While the term “isolation transformer” technically refers to any transformer, it is specifically a transformer that isolates a circuit from an alternating current. An isolation transformer does this by separating two

    • How to Test a Capacitor

      How to Test a Capacitor

      A capacitor is used to store energy so that it can provide power to any kind of electrical appliance when it is needed. Over time, though, the capacitor does begin to wear out and when this happens, its effectiveness in powering the appliance can diminish. Therefore, conducting a simple test on the capacitor can provide

    • Transducer

      Transducer

      The broad definition of a transducer is a device that changes energy from one type into another. However, most transducers change between electricity and another energy type. Transducers also have other names depending on their usage such as probe, detector, pickup, sensor, gauge, and electrode. Chemical Transducers Acidity and alkalinity are measured using a pH

    • Rheostats

      Rheostats

      A rheostat is an electrical component that has an adjustable resistance. It is a type of potentiometer that has two terminals instead of three. The two main types of rheostat are the rotary and slider. The symbol for a rheostat is a resistor symbol with an arrow diagonally across it. Rheostats are used in many

    • BJT Transistors

      BJT Transistors

      Basic diodes are constructed from two semiconductor materials, germanium or silicon, to create a basic PN-junction. When two single diodes are connected to each other back-to-back, two PN-junctions that are connected in series are created. They share a common N or P terminal, which forms the basis of a BJT or Bipolar Junction Transistor. The

      Photodetectors

      A photodetector is a device that imprints the image of an object or scene onto a material. Photodetectors are made in various ways and can be used for different purposes. Most photodetectors fall into the phototube, thermal detector, or camera category. These photodetectors are used for communication, navigation, and record keeping. Types of Photodetectors Phototube
