An alternating current E(t) = 120 sin(12t) has been running through a simple circuit for a long time. The circuit has an inductance of L = 0.33 henries, a resistor of R = 3 ohms, and a capacitor of capacitance C = 0.02 farads. What is the amplitude of the current I?

A resistor with resistance R and a capacitor with capacitance C are connected in series to an AC voltage source. The time-dependent voltage across the capacitor is given by VC(t) = VC0 sin ωt. What is the amplitude I0 of the total current I(t) in the circuit? Express your answer in terms of any or all of R, C, VC0, and ω.

$\bullet$ Consider the circuit sketched in Figure $22.22 .$ The source has a voltage amplitude of $240 \mathrm{V}, R=150 \Omega,$ and the reactance of the capacitor is 600$\Omega .$ The voltage amplitude across the capacitor is 720 $\mathrm{V}$ . (a) What is the current amplitude in the circuit? (b) What is the impedance? (c) What two values can the reactance of the inductor have?
