Question

In the session long projects for this class, you will be asked to conduct experiments in a "virtual" laboratory. For Module 1 you will run a simulation that allows you to investigate current and voltages across resistors in a purely resistive circuit.

Click on the following link to access the simulation .

Fendt, W. (2002). Combinations of resistors (Java simulation). Retrieved on 13 Nov 07 from http://www.walter-fendt.de/ph14e/combres.htm

Run the simulation and do the following things:



2. Find the voltage (V) and currents (A, A1, A2) across the following sets of parallel circuits (see figure

above) where the voltage source is 12 VDC. a. R1=50?, R2=100? b. R1=100?, R2=200? c. R1=200?, R2=400?




Explanation / Answer

total r=r1+r2/3 a)r=50+100/3=250/3 i=i1=36/250=0.144 i2=i1/3=0.144/3=0.048 b)r=100+200/3=500/3 i1=i=0.072 i2=0.024 c)r=200+400/3=1000/3 i1=i=.036 i2=0.012
