Quiz 1: 20 Points – Due 9/14/2010 – 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
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 Coulombs)
c) (5 pts) Compute the charge at 4 Seconds, q(4).
