Question

3. Assuming ideal sources, explain which circuit configurations are allowed and which are not. For the allowed circuits find the currents through and voltages across all circuit components. 3A If? 2A 4A 2Ω 62 42 A 40 Skt2 32 7V 1ον 5V 40 90 7E2 GV 3Ω 5( 2 12

Answer 1

Given, this configuration is not valid. Because in a series circuit current is same but there there are two different current sources with different values 2A & 3A . this configuration is not valid. This configuration Is valid current through 3 ohm = 2A. voltage across 3 ohm = v_3 ohm = 2 times 3 = 6v current through 4 ohm = I_4 ohm = 2A voltage through 4 ohm = v_4 ohm = I times R = 2 times 4 = 8v. current through 2 ohm = I_2 ohm = (4A-2A) = 2A voltage through 2 ohm = v_2 ohm = 2 times 2 = 4v. \r\n current through 6 ohm = I_6 ohm = 4A voltage through 6 ohm = v_6 ohm = 4 times 6 = 24v. current through 5 ohm = I_5 ohm = 4A voltage through 5 ohm = v_5 ohm = 4 times 5 = 20v. this circuit configuration is not valid. bcz in
