Cavity Resonators: A cavity resonators is a piece of waveguide closed off at both ends with metallic planes. Where propagation in the longitudinal direction took place in the waveguide, standing…
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.…
Tirril Voltage Regulator: In this type of Tirril Voltage Regulator, a fixed resistance is cut in and cut out of the exciter field circuit of the alternator. This is achieved…
Three Phase Drives: Single phase drives discussed in the previous section are employed for low and medium powers. When the power of the drive is very large the three-phase converter…
Classification of Fluids: Classification of Fluids are as follows. Ideal fluids and Real or Practical fluids. Newtonian fluids and Non-Newtonian fluids. 1 .Ideal Fluids: Ideal fluids are having following properties. It…
Classification of Printers: Classification of Printers - Character printers and graphic plotters are the two devices used to prepare a permanent (or hard copy) record of computer output. The basic…
5x7 Dot Matrix Led Display Character Patterns: Excellent alphanumeric characters can be displayed by using dot matrix LEDs with an LED at each dot location. Commonly used Dot Matrix Displays…
Types of Single Phase Synchronous Motor: There are two types of single phase synchronous motor, namely, Reluctance Motor Hysteresis Motor Construction of Reluctance Motor and Torque Speed Characteristics: The reluctance…
