    What is Wire wound resistor?

    A wire wound resistor is an electrical passive component that limits current. The resistive element exists out of an insulated metallic wire that is...

    What is Transformer?

    Transformer are capacitors which use a thin plastic film as the dielectric. This film is made extremely thin using a sophisticated film drawing process....

    What is Thermistor?

    A thermistor (or thermal resistor) is defined as a type of resistor whose electrical resistance varies with changes in temperature. Although all resistors’ resistance...

    What is Transistor?

    A transistor is a type of semiconductor device that can be used to both conduct and insulate electric current or voltage. A transistor basically...

    What is Semiconductors?

    Semiconductors are the materials which have a conductivity between conductors (generally metals) and non-conductors or insulators (such ceramics). Semiconductor can be compounds such as gallium arsenide or...

    What is Schottky diode?

    Schottky diode, also known as the hot-carrier diode is a semiconductor diode with a very fast switching action, but a low forward voltage drop....

    What is Relays?

    Relays are the switches that aim at closing and opening the circuits electronically as well as electromechanically. It controls the opening and closing of...

    What is Rectifier?

    The rectifier circuit is the most used circuit because almost every electronic appliance operates on DC (Direct Current) but the availability of the DC sources is limited...

    What is Power Supply?

    A Power Supply is a hardware component that supplies power to an electrical device. It receives power from an electrical outlet and converts the...

    What is Power factor?

    Power factor is an expression of energy efficiency. It is usually expressed as a percentage—and the lower the percentage, the less efficient power usage...

    What is Plastic film capacitor?

    A plastic film capacitor is a capacitor that uses plastic film as the dielectric and aluminum or zinc as the electrodes to store electric...

    What is Oscilloscopes?

    Oscilloscopes or scopes are an important tool in the armory of the electronics engineer or tester. An oscilloscope is an item of electronics test...

    What is Multimeter?

    A Multimeter, also known as a volt-ohm meter, is a handheld tester used to measure electrical voltage, current (amperage), resistance, and other values. Multimeters come...

    What is MOSFET?

    A Metal–Oxide–Semiconductor Field-Effect Transistor (MOSFET, MOS-FET, or MOS FET) is a field-effect transistor (FET with an insulated gate) where the voltage determines the conductivity...

    What is Diode?

    A Diode is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction but...
