Question
For the circuit shown in the figure, the Thevenin equivalent voltage (in Volts) across terminals a-b is ________.
Correct answer
10 to 10
Solution
To find the Thevenin equivalent voltage across terminals a-b, we need to find the open-circuit voltage .Let the top node be and the bottom node be the reference (0 V). The terminals a and b are connected across the parallel combination of the 1 A current source and the resistor. Thus, .Applying KCL at node :Multiplying the entire equation by 6 to clear the denominators:Therefore, the Thevenin equivalent voltage .
