ECE 294 - Lab 11: The Diode and Diode Circuits Quiz

What is a key difference between an ideal diode and a real diode?

• Ideal diodes can operate without power

• Real diodes do not conduct current

• Real diodes have infinite current capacity

• Ideal diodes have zero resistance

What distinguishes a Zener diode from a standard rectifier diode?

• Zener diodes have no voltage drop

• Zener diodes are used for AC circuits only

• Zener diodes can conduct in reverse bias

• Standard diodes can only conduct in reverse bias

What is the purpose of using an incandescent lamp in series with the diode?

• To act as a high power resistor

• To provide illumination

• To reduce voltage

• To measure temperature

How can you determine the reverse current of a diode if the digital ammeter cannot measure it?

• By measuring voltage across a high value resistor

• By using a low value resistor

• By using a different diode

• By increasing the power supply voltage

What should be done to avoid burning the bulb in the diode circuit?

• Use a different type of bulb

• Decrease the voltage supply

• Use a higher wattage bulb

• Stop increasing current when it becomes bright

What is the Zener breakdown voltage?

• The voltage at which the Zener diode conducts in reverse

• The voltage at which the diode conducts in forward bias

• The maximum forward voltage of a diode

• The voltage at which the diode stops conducting

What is the purpose of a diode clamp circuit?

• To amplify the input signal

• To increase the current flow

• To convert AC to DC
