PHY 152 College Physics LabOSDC Circuits We will be using the PhET simulation "Virtual Construction KitACALiuaLLaD." Equipment needed: The PhET simulation at the link. Graph Paper and a ruler, or graphs on R We will be looking at a few basic circuitsl and measuring current through and voltage drop across the elements in them. for this lab. computer Despite the title. this virtual la actually lets us do both AC and DC circuits. Essentially, if we want to use the lab to study DC circuits. we will place batteries instead of an AC power supply. We're going to look at two circuit elementsthe resistor and the capacitorin both series and in parallel. The instruments we have available in this virtual lab include voltmeter and ammeters: the former needs to be connected in parallel with the element(s) it is measuring. the latter in series. Given these instruments, it is easier to begin with simple circuits containing only resistors. After this, we will add in the capacitors. 1. Begin with two resistors in series. Connect a 9.0 V battery to two 10.0 $2 resistors (in series). a) Measure the voltage drop across each of the two resistors. Also measure the current before. between, and after the resistors. b) Change one resistor to 20.0 (2. and repeat the measurements. 2. Now let's do the resistors in parallel. Return the values of both resistors to 10.0 :1, but now place them in parallel with the battery. a) Again, measure the voltage across and the current through each of the two resistors. Also measure the total current leaving or returning to the battery. b) Again. change one resistor to 20.0 Q and repeat these two measurements
