Quiz 1: 20 Points – Due 1/24/2012 – Show Work for Partial Credit
A time varying electric current, I(t), is described in a piecewise linear fashion as shown
below. Knowing that the relationship between charge and current is I(t) = d q(t)/ d t, find
the following:
a) (5 pts) Write the set of equations that describe the current algebraically as a
function of time
b) (10 pts) Write the set of equations that describe the charge, q(t), associated with
this current (Assume that the initial charge, q(0), is -2.5 Coulombs)
c) (5 pts) Compute the charge at 4 Seconds, q(4).
d) (5 pts) Sketch q(t)
