Determination of h Parameters from Static Characteristics: Functional relationships for the CE configuration of total instantaneous collector current and base voltage in terms of two variables (base current and collector…
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…
Hybrid Parameters of Transistor or h Parameters and Hybrid Model: A box representing a two-port network is illustrated in Fig. 11.1. The terminal behavior of a two-port device may be…
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…
Digital Tachometer Working Principle: Digital Tachometer Working Principle technique employed in measuring the speed of a rotating shaft is similar to the technique used in a conventional frequency counter, except…
Reactive Power with Wattmeter: We have already seen earlier that the difference between higher reading wattmeter and lower reading wattmeter yields VLIL sin Φ. So, the total reactive power =…
Power Factor by Two Wattmeter Method: When we talk about the power factor in three-phase circuits, it applies only to balanced circuits, since the power factor in a balanced load…
Three Wattmeter and Two Wattmeter Method: In this method, the three wattmeter are connected in the three lines as shown in Fig. 9.45, i.e. the current coils of the three…
