Consider the circuit (shown below) consisting of an AC voltage source:
V(t)=Vosin(wt) connected in series to a capacitor C and a coil, which has
resistance R and inductance Lo.
(a) Write a differential equation for the current in this circuit.
(b) What angular frequency wres Would produce a maximum
current?
(c) What is the voltage across the capacitor when the circuit is
driven at this frequency?
(d) Information is given that when a dielectric material is inserted
into a capacitor the electric field inside changes. When a
dielectric is inserted into the capacitor, its capacitance changes
by a factor of 4 to C= Co. What is the new resonance frequency?
(e) Now drive the new circuit with the original wres. What is the
phase angle between the current and the voltage?
-V V Vc -
R
C
V(t)=Vosin(wt)
