Materials with higher dielectric constant ratings have ________ resistance to electrical current.

• higher

• equal

• lower

• terrible

Capacitance is governed by all of these EXCEPT ________.

• surface area of the condenser plates

• dielectric material used

• space between condenser plates

• conductor diameter

A capacitor can also be called a ________.

• DRAM

• Condenser

• Farad

What is the unbiased condition of a diode?

• It is at rest with a positive voltage applied to the P region

• It is at rest with a negative voltage applied to the N region

• It is at rest with no voltage applied

• It is at rest with a voltage applied to both the P and N regions

How does the threshold voltage or barrier potential affect the process by which a diode conducts electricity when a voltage is applied?

• It has no effect on the process

• It determines the resistance of the diode at all applied voltages

• It determines the minimum applied voltage required for the diode to begin conducting

• It determines the maximum applied voltage at which the diode can conduct

How does a DC to DC converter differ from a Zener diode in regulating voltage in an electrical circuit?

• A DC to DC converter can step up or step down the voltage as needed, while a Zener diode can only maintain a constant voltage

• A DC to DC converter can only maintain a constant voltage, while a Zener diode can step up or step down the voltage as needed

• A DC to DC converter can be used to isolate the two sides of the circuit, while a Zener diode cannot

• A DC to DC converter can be used to control the input voltage to a transformer, while a Zener diode cannot

VBPWR is a _______ volt buffered power source for certain automotive sensors. (Note: Answer is a number not a word)

Which leg of a transistor is known as the controlling part?

• Emitter

• Gate

• Collector

• Base

Digital signals produce ____________________wave patterns.

Draw the symbol for a diode.
