Question

A resistor R = 4.0 omega, a capacitor C = 1 F and an inductor L
= 4 H are connected in series

Determine the charge on the capacitor and the current on the
circuit at time t, if originally the capacitor is discharged and
the current is 6A

In the following cases:

a) V = 0, classify the current and make the graph

b) V = 120, in this case make the graph of the charge Q (t) and the
current I (t). What happens in both graphs when time tends to
infinity? Explain

c) Now consider an alternating current source given by V (t) = 100
cos(t). Also determine the capacitor charge and current at time
t
