If both the resistors shown (R1 and R2) in the diagram below are of equal size, what is the voltage at the arrow?

  1. 9V
  2. 12V
  3. 18V
  4. 24V

Answer(s): B

Explanation:

The total voltage drop of the circuit must equal the voltage across the battery, which is 24V. Because the resistors are both the same size, each resistor creates half of the total voltage drop: 24/2 = 12. Therefore, the voltage at the arrow is 12V.



A crossover network is used to _____________.

  1. direct the proper frequency range to the right speaker
  2. eliminate noise
  3. filter out high frequencies
  4. filter out low frequencies

Answer(s): A

Explanation:

A crossover network is designed to make sure that the right frequencies get to a speaker so it can reproduce them better.
