EXAM I: 100 Points, Show work for partial credit.
1a. Given I(t) in the graph below, find:
(7pts) The charge, q(t), for 2<t<4 seconds
(6pts) Also, compute q(4 seconds)
1b. The charge delivered to the resistor shown below is described by the following equation:
q(t) = -120 e-5t microCoulombs
(6pts) Calculate I(t).
(6pts) Also, for the diagram shown, if V = 1.2 e-5t Volts, find the value of R, in Ohms using
your value for I(t).
