Experimental Determination of Hybrid Parameters: Determination of hybrid parameters of a general linear circuit has already been discussed. For determination of hybrid parameters for a CE transistor, consider the circuits…
Series Diode Configurations with DC Inputs: The approximate models discussed in preceding section are used for investigation of a number of series diode configurations with dc inputs. This establishes a…
Working Principle of Digital pH Meter | Block Diagram: Working Principle of Digital pH Meter - The Digital Measurement of hydrogen ion activity (pH) in a solution can be accomplished…
Transistor Models and Parameters: T-Equivalent Circuit - Because a transistor consists of two pn-junctions with a common centre block, it should be possible to use two pn-junction ac equivalent circuits…
Types of DC Motor: The commonly used Types of DC Motor are shown in Fig. 5.1. In a separately excited motor, the field and armature voltages can be controlled independent…
Motor Design Parameters: Different parts of a load may be coupled through different mechanisms, such as gears, V-belts and crankshaft. These parts may have different speeds and different types of…
Speed Control of DC Motor: The Fig. 15.38 shows the analog approach to control the Speed Control of DC Motor. A tachometer is used to get the information about the…
Voltmeters and Multimeters Articles: DC Meter: The most commonly used dc meter is based on the fundamental principle of the motor. The motor action is produced by the flow of…
