Compact Fluorescent Lamp (CFL) - Working Principle, Types, Advantages and Disadvantages: A compact fluorescent lamp (CFL), also known as a compact fluorescent light or energy saving light, is a type of fluorescent lamp which combines…
Impedance Matching and Tuning in Waveguide: We know that suitably chosen series or parallel pieces of transmission line had properties which made them useful for providing resistive or reactive impedances. It is the purpose of…
Ultrasonic Transducer: Ultrasonic Transducer (sound vibrations above 20 kHz) are useful when we are concerned with rapid temperature fluctuations, temperature extremes, limited access, nuclear or other severe environmental requirements and measurement of temperature distribution inside…
Arithmetic Instructions in 8051: The Arithmetic Instructions in 8051 of Basic Assembly Language Programming are ADD, ADDC, SUBB and DA The ADD instruction adds a byte variable with the accumulator, leaving the result in the…
Conversion of Hybrid Parameters in Transistor Three Configurations: Some transistor manufacturers provide only the four CE hybrid parameters while others provide CB hybrid parameters. Sometimes, for a specific purpose, it becomes necessary to convert one…
Transition and Diffusion Capacitance: Transition and Diffusion Capacitance - Electronic devices are inherently sensitive to very high frequencies. Most shunt capacitive effects that can be ignored at lower frequencies due to very high reactance (XC…
Precision Full Wave Rectifier: The Precision Full Wave Rectifier circuits accept an ac signal at the input, inverts either the negative or the positive half, and delivers both the inverted and noninverted halves at the…
Equivalent Circuit of Current Amplifier: The input signal in a current amplifier is essentially a current, and thus the signal source is most conveniently represented by its Norton equivalent (Fig. 19.3). The output quantity of…
Optimal Two Area Load Frequency Control: Modern control theory is applied in this section to design an Optimal Two Area Load Frequency Control for a two-area system. In accordance with modem control terminology ΔPc1 and…
Types of Auto Reclosing: Types of Auto Reclosing can be broadly classified in two categories: Medium voltage auto-reclose where continuity of supply is the principal aim. High voltage auto-reclose where the main considerations are of…
