Given: vs, R1, R2. Assume that the op-amp is ideal. Determine the voltage vo. R2 3mA R1 Us

Please I need the exact number that goes to the box after expressing the answer to two significant figures.

Problem 4 a) PEFF R₁ AAA b) Vs 5 V wwwwww R₁ R₂3 Vout 3.3 V Voltage generated by pins of Arduino microcontroller board is 5V. Voltages that can be applied to Raspberry Pi microcontroller boards cannot exceed 3.3 V, otherwise Raspberry Pi board will be permanently damaged. The so-called voltage level shifting is required. One of the ways how this can be achieved is by using the voltage divider circuit as shown in a), and schematically represented in b). Design this voltage divider circuit. Hint: in the voltage divider formula resistance of one of resistors can be chosen arbitrarily, so the other resistor value can be computed. In order not to exceed power ratings of resistors use resistor values not lower than 1 KQ.

39. You and your lab partner have built the circuit shown in Figure 1.56. The three resistors, R1, R2 and R3 all have resistances of 1 k2, while the two voltage sources have 5 V and 3 V (as shown). The circuit has two output terminals, A and B. Answer the following questions about the circuit. (NOTE: The orientation of the voltage sources is important.) (a) What is the voltage drop across R1 R2 R3 A 5 V 3 V B Figure 1.56: The circuit for problem 39. R3? (b) What is the current flowing through R1? (c) Sketch the Thévenin equivalent circuit as seen looking into the terminals A and B. What is the Thévenin voltage, Vth, of the circuit? (d) What is the power supplied by the two voltage sources? (e) In order to safely determine the Thévenin resistance of your circuit, you connect a fourth resistor, R4 = 1 k2, between A and B. Using your trusty yellow DVM, you measure a potential difference across R4 to be 0.4 V. Using %3D
