The best answer is b, 2. One diode is used for each signal polarity.

5. If a diode is used as a power sensor, what happens if the input sign's amplitude isn't high enough for the diode to fully conduct in the forward direction?

a. The diode will completely turn off, allowing no current to pass. b. The diode will pulse on and off. c. The diode will behave like a nonlinear resistor. d. The diode's ability to pass current will oscillate, with a frequency based on stray capacitance. e. None of the above.
