In this problem, we're going to use Ohm's law.
, where i is current, V is voltage, and R is resistance.
From Ohm's law, we can get resistance as:
R = V/i
Substituting the expressions for V and i that we've been given:
In the Circuit in Fig. p7.1, the voltage and current expressions are:
v = 160e–10t V, t > =0+;
i = 6.4e–10t A, t > = 0.
b) τ ( in milliseconds).
d) the initial energy stored in the inductor.
e) the time (in milliseconds) it takes to dissipate 60% of the initial stored energy.
