A semiconductor device that allows current to flow in only one direction is a:

• Transistor
• Diode
• Capacitor
• Inductor

Which type of diode allows reverse current flow at a specific voltage?

• Schottky diode
• Zener diode
• Light Emitting Diode
• Rectifier diode

A Schottky diode is characterized by its:

• High reverse breakdown voltage.
• High power consumption.
• Low forward voltage drop.
• Slow switching speed.

What happens when current flows through a Light Emitting Diode (LED)?

• It generates a magnetic field.
• It stores electrical charge.
• It emits light.
• It significantly increases resistance.

Materials that permit the easy flow of electrical current are classified as:

• Conductors
• Insulators
• Semiconductors
• Superconductors

In conductors, the movement of which subatomic particles facilitates electrical current?

• Protons
• Neutrons
• Atoms
• Electrons

Materials that strongly impede the flow of electric current are known as:

• Conductors
• Insulators
• Semiconductors
• Resistors

The high resistivity of insulators is primarily due to their atoms having:

• Loosely bound electrons.
• A large number of free electrons.
• Mobile ions.
• Tightly bound electrons.

Semiconductors are defined as materials with conductivity:

• Similar to conductors.
• Similar to insulators.
• Lower than insulators.
• Between conductors and insulators.

How does the resistivity of a semiconductor typically change with increasing temperature?

• Resistivity increases linearly.
• Resistivity remains constant.
• Resistivity fluctuates randomly.
• Resistivity decreases.
