Answer:
14.488 amperes
Step-by-step explanation:
The amplitude I of the current is given by
where
= amplitude of the energy source E(t).
Z = Total impedance.
The amplitude of the energy source is 120, the maximum value of E(t)
The total impedance is given by
where
<em> R= Resistance </em>
<em>L = Inductance </em>
<em>C = Capacitance </em>
<em>w = Angular frequency </em>
= inductive reactance
= capacitive reactance
As E(t) = 120sin(12t), the angular frequency w=12
So
and
Finally
