5.6 DETERMINATION OF EQUIVALENTS FOR CIRCUITS WITH DEPENDENT SOURCES

Method-1:

1. Find v_oc by nodal analysis or mesh analysis or superposition principle.
2. Find i_sc by nodal analysis or mesh analysis or superposition principle.
3. Obtain R_o by

Method-2:

1. Find v_oc by nodal analysis or mesh analysis or superposition principle.
2. Assume that a current source of 1 A is applied to the output terminals of the deactivated network such that the current flows into the network at the first terminal. Carry out a node or mesh analysis and find out the voltage appearing at first terminal with respect to second terminal. The numerical value of this voltage gives the ...
