v Two people are debating electron flow versus conventional flow. One of them says that you will get different results predicting polarity of voltage drops in a resistive circuit depending on which convention you use. The other person says that the convention for labeling current does not matter at all, and the correct polarities will be predicted either way. Which of these two people is correct? Explain why, and give an example to prove your point. ANSWER:

Consider the circuit below. Assume that the capacitor is initially uncharged. V1 = 24 V R, = 10 k C, = 10 µF R2 = 30 kN Hint a. What is the initial current through resistor R, when the switch is closed (t = 0)? Current through R2 at t = 0 is mA. b. What is the current through resistor R2 when the capacitor is fully charged, long after the switch is closed (t → 0)? Current through R2 as t → ∞ is mA.
answer C and D The circuit contains four parallel plate capacitors, all initially uncharged and with no dielectric material between their plates. A switch is closed to complete the circuit at time t=0, so current begins to flow at that time and we wait enough time for the capacitors to become (very close to) fully charged. a.
