The op amp shown in Figure P1, is assumed to be ideal, and the output saturation levels are ±10V. Rc is a variable resistor. a. Find an expression for V, in terms of Rg. b. Indicate the resistor(s) that Vo does not depend on, and why? Find the value of Vo when: i) RG = 0 (short circuit), ii) R→ (open circuit) e. Problem2) The switch in the circuit in Figure P2 has been open for a long time before closing at 1=0. Find 1, (1) for 120. Problem 3) Assume that at the instant the 60 mA de current source is applied to the circuit in Figure P3, the initial current in the inductor is -45 mA, and the initial voltage on the capacitor is 15 V (positive at the upper terminal). Find the expression for i, (t) for 120 if Requals 200 £2. 3.3k0 www 60 mA Problem 5) There is no energy stored in the circuit in Figure PS when the switch is closed at t-0. Find v₁ (t) for 120.
