Some values may need to be interpreted from the simulation results (such as the voltage drops across R1 and R3). Input those values obtained in the appropriate columns of Item 3 of Table L If you have not used Pspice, you may want to go through the tutorials in "Getting Started with Orcad Pspice" and use the Penn State Remote Lab tools to get access Pspice. to Print out (or take Pspice and attach it to the end of this lab report. It should show the values obtained in Item 3 of Table I "printscreen" of) the circuit schematic from Orcad m a n. Do resistors R2 and R4 have the same voltage across them? Do resistors R2 and R4 have the same current through them? Explain in the space provided. o. In the space provided, compare your experimental, theoretical and simulation results. 2. Design a circuit to provide 1mA of current through the buzzer and 10mA of current through the red LED. Some trial and error (an iterative approach) may be necessary. Refer to Lab 3 for a refresher on the red LED. You don't have to provide a circuit like the one earlier. Indicate how you solved the problem, including providing a circuit schematic of your system Record the measured values of current through the LED and buzzer in the appropriate columns of Table II. Determine the voltage both the buzzer and the LED with the circuit working, and record in the appropriate columns of Table II. across Feel free to use any of the following online schematic drawing tools: www.circuitlab.com/editor http://www.digikey.com/schemeit# Item-3- M: a screen capture of the Pspice simulation.

As we can see from table

NO resistors R2 and R4 dont have same voltage or current

if we see the circuit with out ammeter or voltmeter we can tell resistors R2 is in parallel connection with resistors R3 and R4 which are in series there fore voltage across R2 will be same as sum of voltage of R3 and R4 not R4 only. Current in R2 and R4 will be equal if resistor value of R2 is equal to sum of resistor value of R3 and R4 here R2 is 2k ohms and R3+R4 is 1.51K ohms which are not equal, there fore their current are not equal.
