Overview
Objective:
Methodology
Questions to be answered in your report:
- Does your graph of τ vs. R pass through the origin? Should the graph necessarily pass through the origin? What does a non-zero intercept signify?
- Discuss your observations of [VC(t) + VR(t)] for both the charging and discharging processes.
- In one of the current versus time graph, choose a current (near the time ~ 0 sec), say I1. Now find the current which is 1/e (= 0.37) of I1. How long does it take to change from I1 to 0.37 I1? Compare it with time constant.
- --
- Do your experimental values for the series and parallel combinations of capacitors agree with the theoretically calculated values? Discuss in terms of the experimental errors involved.
- Your capacitors were charged to a maximum voltage of 5 volts. In each of the four cases (that is for the individual capacitors and for the series and parallel combinations), when the capacitors were fully charged, what was:A. The charge (in microcoulombs) stored on the plates of each capacitor.
