This area cover guidance about electrical component and electronic devices. it also cover use of component in circuits design with benefit and losses of miss-configuration of its value. its also cover active and passive component and its example with projects.
How do you bias photodiode?
How do you bias photodiode? As the applied reverse bias increases, the photodiode current increases sharply. The blocking voltage applied at this point is called the breakdown voltage. This is…
Resistance
Resistance Resistance is defined as the opposition against current flow. Some materials offer more Resistance as others. An example for is rubber. Rubber has more resistance in Compared to copper…
What is an NPN transistor used for?
The most commonly used configuration of the transistor is the NPN transistor. We also found that the bipolar transistor intersections can be biased in one of three different ways –…
What are the types of transformers ?
Transformers are essential devices in electrical systems, designed to transfer electrical energy between circuits through electromagnetic induction. There are various types of transformers, each serving specific purposes in different applications….
Why is amplitude modulation used ?
Amplitude modulation (AM) is a modulation technique widely used in communication systems for various reasons, providing advantages and fulfilling specific requirements in certain applications. Here are detailed explanations of why…
Why is a circuit breaker connected in a series with load ?
A circuit breaker is connected in series with a load primarily to provide protection for the electrical circuit and the connected devices. The placement of a circuit breaker in series…
What are forward biased and reverse biased diodes ?
Diodes are semiconductor devices that allow the flow of electric current in one direction while blocking it in the opposite direction. The terms “forward biased” and “reverse biased” refer to…
Can a motor run without a capacitor ?
The operation of a motor without a capacitor depends on the type of motor and its design. Capacitors are commonly used in single-phase induction motors to improve their starting and…
Is it wrong to believe that Transistors BJT are current controlled ?
The notion that bipolar junction transistors (BJTs) are current-controlled is a common misconception. In reality, BJTs are voltage-controlled devices. The input voltage at the base-emitter junction controls the flow of…
