1. (Exercise 1.10, page 18) The current entering the positive terminal is
dq d 4t 4t 4t i(t)= dt = dt 30e
=(4)(30e )=120e
mA
The unit is mA because the charge is expressed in mC. The power in the element is
p(t) = v(t)i(t) =

n the following, we will use the notion (R1 R2) to denote the equivalent resistance of R1 and R2 connected in
parallel. We know that (R1 R2) =
R1R2 . In the same way, three resistance in parallel will be denoted by (R 1
R2 R3).
Dierential Equations
The behaviour of RLC circuits is described
by dierential equations.
The relationship between any voltage or
current in the circuit is related to any other
voltage or current in the circuit by a
dierential equation.
These dierential eq
