The reciprocal of slope of current-voltage curve at Q-point gives ___________

Electronics and Communication Engineering (ECE) : Analog Electronics - Quiz(MCQ)

AC resistance

Nominal resistance

Minimum impedance

Maximum dynamic resistance

Correct Answer : Option (A) : AC resistance

Explanation : Reciprocal of slope of I-V graph at q-point gives AC or dynamic resistance. The inverse of slope will be change in voltage by change in current which is known as dynamic resistance.
