Understanding Forward and Reverse Bias in Semiconductors

What is the correct connection for a forward bias in a semiconductor?

• Positive to p-type, negative to n-type

• Positive to n-type, negative to p-type

• Both terminals to n-type

• Both terminals to p-type

What is the outcome of a forward-biased connection in terms of current flow?

• Current flow is unpredictable

• High current flows

• Low current flows

• No current flows

In a diode symbol, what does the arrow represent?

• The voltage level

• The direction of current flow

• The direction of electron flow

• The type of semiconductor

In a forward-biased diode, what is the relationship between the arrow direction and current flow?

• They are unrelated

• They are the same

• They are perpendicular

• They are opposite

What happens to the current when the voltage in a forward-biased circuit exceeds the barrier voltage?

• The current decreases

• The current stops

• The current increases

• The current remains the same

How is reverse bias achieved in a semiconductor?

• By connecting positive to p-type and negative to n-type

• By connecting positive to n-type and negative to p-type

• By increasing the voltage

• By decreasing the voltage

What is the primary characteristic of a reverse-biased circuit?

• Alternating current flow

• High current flow

• No or very low current flow

• Unstable current flow

What is the effect of reverse bias on the depletion layer?

• It becomes narrower

• It remains the same

• It becomes wider

• It disappears

What happens to the barrier voltage in a reverse-biased semiconductor?

• It decreases

• It remains constant

• It fluctuates

• It increases

What role do minority charge carriers play in reverse bias?

• They cause high current flow

• They have no effect

• They contribute to a very low current

• They reverse the current direction
