A series LCR AC circuit is at resonance. It contains a resistor of 16 W, a capacitor of 0.35 mF, and an inductor of 90 mH. If an effective (rms) voltage of 150 V is applied, what is the effective (rms) current when the circuit is in resonance?
 a. 9.4 A
  c. 5.0 A
  b. 3.3 A
  d. 16.1 A

Question 2

If I0 = 10-12 W/m2 is the threshold of hearing, a sound with intensity I1 = 10-10 W/m2 will give a certain decibel level. Suppose a new sound has an intensity I2 = I12/I0 . What is the new decibel level?
 a. 40
  c. 10,000
  b. 20
  d. It will square the decibel level.
