You measure the capacitanceC1of a capacitor by doing thefollowing: First connect capacitorsC1andC2in series to a power sup-ply that provides a voltageVthat can be varied. The capacitance ofC2is known to be3.00mF. Then vary the applied voltageV, and for eachvalue ofVmeasure the voltageV2acrossC2. After plotting your data asV2versusV, you find that the data fall close to a straight line that hasslope 0.650. What is the capacitanceC1?
Suppose we have a capacitance C discharging through a resistance R. Define and give an expression for the time constant. To attain a long time constant, do we need large or small values for R? For C?
