Theory: -
Kirchoff’s Current Law
Kirchoff’s Current Law states that "in any electrical network the algebraic sum of the currents meeting at a point is zero".
Kirchoff’s Voltage Law
Kirchoff’s Voltage Law states that, "In any electrical network the algebraic sum of the product of currents and resistances in each of the conductors in any closed path plus the algebraic sum of the emfs in that path is zero.
Procedure:-
The circuit diagram is drawn by loading components from the library to Schematic Editor page in EDWinXP Project Explorer. Wiring and proper net assignment has been made. The values are assigned for relevant components. Kirchoff’s current law and Kirchoff’s voltage law circuit diagrams in Mixed mode simulator are shown below.
Mixed Mode Simulator is enabled from Preferences menu. The circuit is preprocessed. The desired test points and waveform markers are placed. The Transient Analysis parameters have been set. The Transient Analysis is executed. The test points display the values of the current through the resistors. Hence we can prove the Kirchoff’s Laws.
The variation of current through the two resistors with respect to
variation in voltage is obtained by performing DC Sweep Analysis. To perform DC Sweep
Analysis, a current waveform marker is placed at the resistor node. The sweep parameter
(voltage) for input source is set in the Analysis window. The applied voltage is swept
from an initial value of 0 to final value of 10V in steps of 10mV. The DC Sweep Analysis
is executed and the corresponding waveforms are observed in the Waveform Viewer.
Result:-
The output waveform may be observed in the waveform viewer The DC Sweep Analysis results are shown below.
