Homework 5Due: Friday, September 21In the circuit of Figure 1, suppose V2= 45V . Find the voltage produced by thesource Vs, the current flowing out of the positive terminal of the source Is, and thepower delivered by the source.Figure 1: Model circuit for Problem 1.2Consider a series voltage divider circuit whose total resistance is 1600 Ω as illustratedin Figure 2. Suppose that V1= 0.75 Vsand V2= 0.25 Vs, and find the values of R1,R2and Rs.1Figure 2: Model circuit for Problem 23Figure 3 shows a Wheatstone bridge circuit that is commonly used in a variety ofmeasurement equipment. the bridge circuit is said to be balanced if RaRd= RbRc.In this case, the voltage Vout= 0 for any input voltage Vin.(a) Use voltage division to compute the voltages Vband Vd. Show thatVd=RdRc+ RdVin(b) If Vout= 0, then what must be true about Vband Vd? Show that Vout= 0 if andonly if RaRd= RbRc.(c) Suppose that RaRd= RbRcand a 3.5 Ω resistor is connected across the Voutterminals. Find the current through the 3.5 Ω resistor.(d) Suppose Vin= 24 V, Ra= 3 Ω, Rb= 6 Ω, Rc= 2 Ω, and Rd= 2 Ω. Find Vout.2Figure 3: Wheatstone bridge circuit.4In the circuit of Figure 4, it is required that I1= 0.5 Iin. Find the resistance R (inΩ), the equivalent conductance Geq, the current I2in terms of Iin, and the voltageVinin terms of Iin.Figure 4: Model circuit for Problem
