Lab C242: C S Simple C Circuits , Week 2 For thiss section, yo ou need onlyy fill out thee accompannying data sheet. No othher write-upp is needed.. y will find d 3 carbon rresistors, mo ounted in doouble-banan na mounts. At yourr position, you Measurre and recorrd on the datta sheet, thee resistancess of the 3 reesistors withh your DMM M. Build thhe followin ng circuit, using u the 3 resistors and the DC power suppply (which h acts like a battery)). Set the vo oltage Vo to o about 10 V and measuure Vo withh the DMM. You can put p the threee resistors in any ord der in the cirrcuit, just be sure to reccord which is which. ges across each of the Measurre the voltag three reesistors. (V1 = voltage aacross R1, ettc) Computte the currents throughh each of thee three reesistors, and d record answers in mA A (I1 = currrent thru R1, etc.) K s voltage law w (the loop law) and Kirchhoff’s K c current law (the junctioon law). Is Verify Kirchhoff’s there anny discrepan ncy? If so, explain. e urrent through the batteery. Does thhis agree witth your earllier measureements?

Explain in writing, and then check your prediction experimentally with your circuit. Experimental Result:
