Which of the following is correct about Hall Effect in electronic circuits?

Electronics and Communication Engineering (ECE) : Electronic Devices and Circuits - Quiz(MCQ)

Hall voltage is directly proportional to the charge density

Hall voltage is very weak in metals as compared to semiconductors

Hall voltage is inversely proportional to the intensity of the magnetic field

Intrinsic semiconductor has a positive temperature coefficient of hall constant

Correct Answer : Option (B) : Hall voltage is very weak in metals as compared to semiconductors

Explanation : Metals have an ocean of electrons. So, there is very little difference between positive and negative charges in metals. Thus, Hall voltage is very weak in metals as compared to semiconductors.
