Thought Experiment: Explain what is physically happening to the charge in the RC circuit during charging and discharging cycles (i.e. Why does the capacitor charge/discharge quickly at first but slows down with more time? Where is the charge going?). In the DC Electrical Circuits lab, we used the analogy of water flowing through a pipe to visualize Ohm's law can you extend that analogy to the RC circuit? * Thought Experiment: Explain what is physically happening to the charge in...
