Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFStatic resistance of the diode
The resistance offered by the diode when connected in forward and reverse bias with a DC supply is known as the static resistance.
The static resistance of the diode is the ratio of diode voltage to diode current.
The static resistance is given by:
\(R_{DC}={V_D\over I_D}\)
Dynamic resistance of the diode
The resistance offered by the diode when connected in forward and reverse bias with an AC supply is known as a dynamic resistance.
The dynamic resistance of the diode is the ratio of the change in diode voltage to the change in diode current.
The dynamic resistance is given by:
\(R_{AC}={\Delta V_D\over \Delta I_D}\)
