Solve the following question:
Question 1: What percentage of the final current I0 flows through an inductor L in series with a resistor R, three time constants after the circuit is completed? (You do not need to enter any units.)
%
Question 2: What is the characteristic time constant of a 28.0 mH inductor that has a resistance of 3.10ohm?
(in ms)
Question 3: If it is connected to a 6.0 V battery, what is the current after 14.5 ms?
(in A)
Please show all work and steps I am really trying to learn this for my test.
