An ac source of maximum voltage V0 = 30 V is connected to a resistor R = 50 , an inductor L = 0.6 H, and a capacitor C = 20 F.

What is the maximum charge on the capacitor when the frequency of the source is set to the resonance frequency of the circuit? A)

1.0 mC
B)

0
C)

2.1 mC
D)

4.2 mC
E)

8.4 mC

Question 2

An unknown resistor is wired in series with an ammeter, and a voltmeter is placed in parallel across the resistor only. This network is then connected to a battery.

If one computes the value of the resistance by dividing the voltmeter reading by the ammeter reading, the value obtained A)

is less than the true resistance.
B)

is greater than the true resistance.
C)

is the true resistance.
D)

could be any of the given answers. It depends on other factors.
