Question

Here are some questions you should address at some point in your analysis: why is the voltage vs. time graph an exponential curve instead of a straight line? (Discuss this question using English, not math.) Does It make sense that increasing that resistance causes the time constant to increase? Was the final voltage acquired the capacitor affected by the size of the resistor, and does that result make sense? Finally, as usual, discuss error sources and any possible ways to improve the lab procedure.

Explanation / Answer

The voltage vs time graph in RC circuit is exponential but not linear, because with time, the charge on the capacitor builds up, causing resistance in the motion of further current, and hence with time this resistance to current from charge on capacitor keeps on increasing and the voltage keeps on building up slowly in the capadcitor, the increase in voltage decreasing over time and hence the exponential graph of voltage vs time

as the time constant depends on both on resistance and the capacitance, so changing thevqalue of resistor does change the value of the time constant. The final voltage does depedn on the resistor, as potential drop acroiss the resistor affects the final voltage as well

Manual errors, like during tabulating the results, and random errors due to environmental factors, etc can creep in the final results and must be taken care of
