Problem 3 - In this problem, you will be working on the node concept in a circuit as well as concepts of parallel and series combinations of resistances. A battery modeled as a voltage source in series with a resistance, is connected to a circuit as shown below. First, you need to simplify the circuit by finding the equivalent resistance, Reg "seen by the battery. Then, you will find is and calculate the power delivered by the battery Follow the steps given below to solve this problem: Battery Vs = 5[V] RS 130) RA= 1610) R = 240) Ri= 11[0] w R = 33[0] R2 = 27101 R3 = 16021 W a) Color code and label the nodes (two of them are already labeled as A and B) on the circuit shown above and verify that there are a total of 4 nodes in this circuit. For a wire connecting devices, being straight or twisted does not make any difference since we assume that the wire resistance is equal to zero. The shape of a wire does NOT matter! b) Look at your color-coded circuit. Identify all of the parallel resistors and calculate the equivalent resistance for each parallel combination. Show your calculations in the following table. There will be two sets of parallel combinations. Remember: if two resistors are in between the same nodes, then they are connected in parallel. Redraw the circuit with parallel resistors combined together. Redraw Circuit Rp1 RPZ c) The circuit you got in step (b) has two resistors in series. Identify them, and calculate the equivalent series combination (Rs). Remember: if two resistors share the same exact current, then they are connected in series. Combine the two series resistors and redraw the circuit. Redraw Circuit RSER d) Identify the two resistors in parallel in the circuit redrawn in step (C). Calculate the parallel combination which will give you the value of Reg. Combine the parallel resistors and redraw the circuit. Redraw Circuit REQ e) Now that the circuit is simplified, use KVL and Ohm's Law to find is and the voltage across the battery (which happens to be the voltage across Req). When applying Ohm's Law, pay attention to sign convention f) Calculate the power delivered by the battery. Remember that the battery is represented by Vs and Rg together. Therefore, the total power delivered by the battery will be equal to the power delivered by v, and power delivered by Rs added together. Show that power delivered by the battery is equal to the power absorbed by Reg.
