Unformatted text preview: below. Section 9.7 Source Transformations and TheveninNorton Equivalent Circuits Problem 4 Norton equivalent circuit The circuit shown below is represented in the frequency domain by a Norton equivalent circuit. When an inductor having an impedance of j100 Ω is connected across the device, the value of V o is 100 ∠ 120˚ mV. When a capacitor having an impedance of j100 Ω is connected across the device, the value of I o is 3 ∠ 210˚ mV. Find the Norton current I N and the Norton impedance Z N for the unknown device in the box. Problem 5 Operational Amplifiers in the frequency domain The opamp shown in the above circuit is ideal. Find the steadystate expression for v o (t) when v g =20cos(10 6 t) volts....
