10 Questions
What is a positive hole in the context of semiconductors?
A gap left behind when an electron breaks free
What is the main difference between intrinsic and extrinsic conduction in semiconductors?
Intrinsic conduction occurs in pure semiconductors, while extrinsic conduction occurs in doped semiconductors
What is the effect of doping a semiconductor with Phosphorus?
It increases the number of free electrons available for conduction
What type of semiconductor results from doping with Boron?
P-type
What is a thermistor in the context of semiconductors?
An electrical component whose resistance decreases rapidly with increasing temperature
What is the depletion layer in a p-n junction?
A region at both sides of a P-N junction that contains no free majority charge carriers
What is the junction voltage in a p-n junction?
Answer (A and B)
What happens to a diode connected in forward bias?
It will allow current to flow once the junction voltage is exceeded
What happens to a diode connected in reverse bias?
It will not allow current flow and will act as an insulator
What is the role of a diode in a rectifier?
To convert a.c. to d.c.
Learn about semiconductors, substances with resistivity between conductors and insulators. Understand how temperature affects resistance and conductivity, and how electrons gain energy to allow current flow in semiconductors like Silicon.
