Answer:
14.488 amperes
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
R= Resistance
L = Inductance
C = Capacitance
w = Angular frequency
= inductive reactance
= capacitive reactance
As E(t) = 120sin(12t), the angular frequency w=12
So
and
Finally
