LED Physics and LED Science Explained Briefly by Article

As per LED Chemistry, Silicon Germanium bandgap semiconductor materials are not suitable for LED because the very higher percentage of electrical energy is to be converted into thermal energy hence emission of light is negligible.In silicon germanium semiconductor diodes electrons and holes recombined non-radiative radiation.Since

digital electronics,digital signal

Digital Electronics Basics and Digital Signal Fundamentals

Before the study, of Digital Electronics, We need to know Analog Signal was represented by a periodic sinusoidal wave.There is nothing any discontinuous point exists, meaning absolutely continuous with respect to time. Now creating a discrete point with same unit time interval on continuous analog

analog devices,analog signal

Analog Devices Basic and Analog Signal Fundamentals

Before the study of the analog devices, we would need to study the characteristics of the analog signal.Information which is to be converted into the electrical form of signals and suitable for transmission by using analog devices from one place to other is called Signal. There

Renewable Energy and Sustainable Energy for the Future

Before study Renewable Energy OR Nonconventional Energy OR sustainable energy, we have to know non-renewable energy. Non-renewable energy is defined as, from a source that is exhaust when used. Such as, electrical,mechanical,thermal,chemical,optical,magnet energy etc.As Renewable Energy or Nonconventional Energy Definition, from a source that is

sensor

Sensor Science and Technology to Analyze the Signals

Sensor OR Actuator detects & measures the signals. Classification of signals with examples into six categories based on energies generated & received, Detect & Measured by Sensor OR Actuator. 1) Mechanical 2) Thermal 3) Electrical 4) Magnetic 5) Radiant 6) Chemical The explanation is based on INSTRUMENTATION ENGINEERING

transducers

Transducers Technology and Working Principle of the Devices

As properties of the transducer biology, Transducers are the machine which is to be used as energy converter to converts one energy form to another energy form.Another way, the device by which non-electrical input quantity to be converted into electrical quantity is called Electrical Transducer.

Instrumentation Engineering with Electronics Engineering

Instrumentation Engineering which deals with the artistic & scientific measurement of Mechanical, Electrical & Electronic parameters. It is also controlled and measures the process variables within a production or manufacturing area.As well as measurement of the process variables used in industries is Level, Pressure, Temperature,

extrinsic semiconductor

Extrinsic Semiconductor Conductivity with Temperature

Conduction of current in the intrinsic semiconductor is poor at normal room temperature, the extrinsic semiconductor can do so.Then, the n-type semiconductor is not useful and inapplicable for electronics device apps technology.Then, very much required to add a small amount of impurity to the intrinsic

intrinsic semiconductor

Intrinsic Semiconductor Conductivity with Temperature

Semiconductors are classified as 1) Intrinsic semiconductor (pure) 2) Extrinsic semiconductor (impure). An intrinsic semiconductor is an undoped pure semiconductor.The intrinsic semiconductor materials that electrical conductivity is increased with increases in temperature, is also called Intrinsic Semiconductor (pure).Under the influence of applied electric field or thermal energy, the covalent bonds
