RL Circuit (2)
•The time
constant t of a circuit is the time required for the response to decay by a factor of 1/e or 36.8% of its initial value.
• i(t) decays faster for small t and slower
for large t.
•The general form is very similar to a RC source-free circuit.
A general form representing a RL
where
