2. What is natural response?
 It describes the “discharging” of inductors or
capacitors via a circuit of no dependent
source.
 No external source is involved, thus termed
as “ natural” response.
The effect will vanish as t
 The interval within which the natural
response matters depends on the element
parameters.

3. The natural response of an RL circuit can best be described in terms of
the circuit shown

9. Exercise 2:At t=0 the switch in the circuit shown moves instantaneously
from position a to position b.

12. Calculating the natural response of an RC circuit can be summarized
as follows:
Ex: The switch in the circuit shown in Fig has been in position x for a long
time. At t=0 the switch moves instantaneously to position y. Find

16. Exercise: The switch in the circuit shown has been
closed
for a long time and is opened at Find
