The frequency of an oscillation is equal to the reciprocal of the period:
where
f is the frequency
T is the period
In our problem, the period is T=8.01 s, therefore the corresponding frequency is
where

T is the period
In our problem, the period is T=8.01 s, therefore the corresponding frequency is
Explanation:
It is given that,
Inductance of the inductor,
Resistance of the resistor, R = 10 ohms
(a) Let is the time constant of the circuit. It is given by :
(b) The current equation in RL circuit is given by :
I' = 0.99 I
t = 4.6 ms
Hence, this is the required solution.
