Now if you want to turn off the dependent source turn it off, no problem, and if you find it easy to leave it on, then that is also fine, since , the linearity is followed by the elements and voltage and current function. ?�ٍS��s�4�N�[&��}x?�_��`.�1�q�����1`o (�~� �о�D@Q;A�.nδ��I]�TC^� �_��d���}|Ok@�{�P�`�M�����`���ƃ�{뀻�xl���W;�4�.��>G�vT+���J��=-m��i�{i(kR�1�ܲ�����G�W�V-�4��q-!�7iJ�)��Ό�����ڐ�cQ���LRe��� �����cZR�,����Ā('0��.

Since I began studying, I was taught that when analysing a circuit using multiple sources, independent sources could be turned off, meaning that I could transform a voltage source into a short, and a current source into an open circuit and analyze the circuit by how each individual source acts on it.

Normally I would leave the dependent source on, turn off the 4A current source and find Vx1, then I would turn off the 6A current source and find Vx2, add them up and find Vx. Finally, I turn off all sources but the 4A current source: Using the same procedure as above, by current divider I find Vx3: Finally, the total voltage Vx is the sum of each individual voltage Vx (Vx1, Vx2, Vx3): $$Vx = Vx1 + Vx2 + Vx3 = -3.2Ix + 9.6 + 6.4$$. The
Both the output of the circuit and the value of each dependent source are solved for. %�쏢 Solution I. The current source should be replaced with open circuits, as … Superposition's 'turn off all sources but one' requires careful interpretation when a circuit contains dependent sources. Again, I think that by doing this, we find out what the contribution of the dependent source to the circuit will be once everything is turned on, if we just stay with what the contribution to the circuit is when everything is off, it will of course be zero. stream the answer is to do the analysis easily. @=�(�{I�����ƣP(��?����'-�я�w/������Ë����ߧ�/_��bn:�/t�O���O^�y�6�2��^��a���O�al���ջ�}��p��e�>�u���7#����˷������y�77�S��M����vh�����
As a simple example using superposition of a dependent source consider the following circuit: By superposition, we can write the equation for \$V_x\$ by inspection: $$V_x = V_s\frac{R_2}{R_1 + R_2} + 5i_x R_1|| R_2 $$, $$V_x = V_s\frac{R_2}{R_1 + R_2} + 5 \frac{V_s - V_x}{R_1}R_1|| R_2$$. <> EC7Rv��2��i���9�`a�Dl4�"6K��Z���`r���!��A�jX��)G"��WVp)�u2�>�6���|rj�uÄ�2#�ԮΩv����|��ģT8�ЇZ� Bڇ�lв�R�-�,�� ��V�v�K4ׁ��:��sU�dr0Y�������rׁ�u_-S�Fȹ:��0�i@�p�����Ň���&9E2H��e���j��������b��7r�.LPY�P�ׄEs�[��@h_c4��6���3|u i�kG,�Մ�j��f��%�QSl���Mj?�^��V� 4#YpA@�]��`�=��!����v� I dont think its cheating, in my opinion, mathematically speaking theres nothing in this case that tells you when you can solve for a numeric answer. 5 0 obj From this limited survey, it is clear that circuits texts <>
source is present, it is never deactivated and must remain active
This can onlynean Ix is zero. ITS AMAZING, it really opens up a world of possibility using superposition just like I did in this example.
