Semiconductor Basics Quiz Practice Quiz…

Q: Which band contains the valence electrons?

Valence Band — The Valence Band is the highest occupied energy band and contains the valence electrons.

Q: What is the Forbidden Gap?

The space between the valence and conduction bands. — The Forbidden Gap is the energy difference between the valence and conduction bands.

Q: How does the Forbidden Gap relate to a material's conductivity?

A larger gap indicates lower conductivity. — A large forbidden gap hinders electron movement, thus reducing conductivity.

Q: What type of material has a large forbidden gap?

Insulator — Insulators have a large forbidden gap, preventing conduction.

Q: Which of the following is an example of a semiconductor?

Silicon — Silicon is a common example of a semiconductor material.

Q: What is the unit for measuring current?

Amperes (A) — Current is measured in Amperes (A).

Q: What is Ohm's Law formula?

V = I * R — Ohm's Law states that Voltage (V) = Current (I) multiplied by Resistance (R).

Q: What does resistance oppose?

Current flow — Resistance opposes the flow of electrons (current).

Q: What is the potential difference measured in?

Volts — Potential difference is measured in Volts.

Q: What is the relationship between the valence and conduction bands in a conductor?

They overlap, with no forbidden gap. — Conductors have overlapping valence and conduction bands, allowing free electron flow.
