For the circuit shown in Figure $1,$ select $R_1=120k,R_2=47k,R_3=100k$ and $R_4=120k$ based on their nominal value $($color coding$).$ Measure the resistance of each resistor using the DMM$.$ Write down the nominal and measured values in the answer sheet Use the measured values in all CircuitLab simulations.

Figure $1.$ Series$/$Parallel resistive network.

a$.$ Simulation: Design the circuit in Figure $1$ using CircuitLab. Add a voltmeter across $R_4,$ to measure its voltage, and ammeters in series with $R_1$ and $R_4$ to measure the current through both elements. Use the measured resistor values. Include a snapshot of your circuit design with the volt$/$current meters in your answer sheet. CircuitLab allows you to export images in PNG File $>$ Export PNG$).$
