Definition: Waveguides are a special category of transmission line that is used to guide (direct) the waves (radiation) along the length of the tube. These are typically a hollow metallic tube that acts as the medium to transfer or transmit power. Optical fibers are a type of waveguide more specifically we can say dielectric waveguide …
Definition: Transducers are the device that is used for the conversion of energy from one form to another different but equivalent form. In terms of instrumentation, more specifically we can say, transducers are the devices that change non-electrical quantity into its electrical equivalent form. The converted form of energy by any transducer can also be …
The crucial difference between conductor, semiconductor and insulator rely on their level of conductivity. Conductors are basically the materials that allow easy flow of electric current, hence exhibiting high conductivity, semiconductors are the materials that possess moderate conductivity. As against, insulators are the materials that prevent the flow of charge through them, thus exhibiting low …

The polarity of the applied external potential (voltage) to any device is characterized as forward and reverse biasing. The crucial difference between forward and reverse biasing is that in forward biasing p region of the device forms a direct connection with the positive side of the battery and n region is connected to the negative …
Definition: Transmission lines are the conductors that serve as a path for transmitting (sending) electrical waves (energy) through them. These basically forms a connection between transmitter and receiver in order to permit signal transmission. Transmission lines in microwave engineering are known as distributed parameter networks. As their voltage and current shows variation over its entire …
Both half adder and full adder comes under the category of combinational logic circuits that are used for arithmetic operations. However, there exist many differences between the two. The major difference between the half adder and the full adder is that the half adder operates on 2 inputs. On the contrary, full adder operates on …
Both diode and transistor are semiconductor devices and are the major part of electronic circuitry. However, there exist several differences between the two. The major difference between diode and transistor is that a diode is a 2 terminal device formed by merging p and n-type semiconductor material. As against, the transistor is a 3 terminal …
Half Wave and Full Wave Rectifiers are the two categories of rectifier circuits. The crucial difference between Half Wave and Full Wave Rectifier is that a half wave rectifier converts only one-half cycle of the ac input supplied into pulsating dc signal. As against a full wave, rectifier converts both halves of the applied input …

Definition: NPN transistor is a type of bipolar transistor that has 3 layers and is used for signal amplification. It is a current controlled device. NPN is an abbreviation used for a negative positive negative transistor. This means a p-type semiconductor is fused between 2 n-type semiconductor material. It has 3 regions namely emitter, base …
Definition: LED is a PN junction diode, that emits light when a certain potential is provided to the diode. LED is the short form for Light Emitting Diode and is a forward-biased device. This means it operates only when a forward voltage is applied to it. It is a semiconductor device whose operating principle is …
