Document Summary

Problem set #9 (total 4 problems: 5 pts each) P 1 the circuit in figure p 1 contains a current-controlled voltage source. This circuit will be stable if the th venin equivalent resistance of the circuit connected to the inductor is positive. The th venin equivalent resistance of the circuit connected to the inductor is calculated as i t. 400 ( ) i t r i t. The circuit is stable when r < 400 w. P 2 the voltage source voltage in the circuit shown in figure p 2 is vs(t) = 8 + 12u(t) v. Solution: simplify the circuit by replacing the parallel capacitors by an equivalent capacitor and by doing a couple of source transformations: For t < 0 the circuit is at steady state so the capacitor acts like an open circuit. The voltage source voltage is 6. 4 v, so v.
