Network Theorem Trainer Model NW-3 is used for verification of the two theorems. They are Kirchoff's voltage and current law and study of Millman?s theorem. In order to perform these, the trainer has necessary facilities, like provision for creating 4 different voltage sources, assorted values of resistors, center-Zero current and built in power supplies. Experiments are performed by using patch cords. Kirchoff's Voltage and Current Law: -
NODAL or LOOP analysis are complimentary to each other. In Loop analysis, we write Kirchoff's Voltage Law (KVL) equations and solve for unknown branch currents. In Nodal analysis, we write Kirchoff's current law (KCL) equations and solve for unknown node voltages. Each is a powerful technique and we normally employ the technique that will readily solve for the desired unknown circuit parameter. Millman?s Theorem:-
In a network system, multiple current sources which are in parallel can be represented by a single current source, having the sum of the individual source currents and the resistance of the parallel combination of the individual source resistance. Specifications:
Voltage source : Provision to create four different voltage sources @ 50mA each
Fixed +5V DC @ 300mA
Meter : 25-0-25mA analogue current meter
Passive components : Suitable value resistors to perform the above task
Enclosure : The entire instrument is housed in an ergonomically designed
cabinet.
Note: It is desirable to have an external Digital multimeter. |
