1. The problem statement, all variables and given/known data I have finished this and gotten an answer, but I have no solutions on hand and would like to see if anyone else gets the same answer :] A 2-nF capacitor with an initial charge of 5.1 microCoulombs is discharged through a 1.3- kiloOhm resistor. (a) Calculatue the current in the resistor 9 microseconds after the resistor is connected acorss the terminals of the capacitor. (b) What charge remains on the capacitor after 8 microseconds? 2. Relevant equations I(t) = - Q/RC(e^(-t/RC)) q(t) = Qe^-t/RC 3. The attempt at a solution (A) Find the current through the resistor. So I differentiated equation one to get I = Q (e^(-t/RC) = 0.16 microAmperes... (B) Differentiate so q = (-Q)(-RC) (e^(-t/RC)) = 6.11 E -11 C My answers seem way too small to me. So my question is, was I supposed to differentiate?? Forgive my ignorance, but what does I(t) mean? Is it the same as dI/dt? Also, if I do not differentiate the question seems exceedingly simple (it's worth 10 marks.) Is there something in my process that I am over-simplifying? Thanks so much to everyone in advance.
