Question

In a diode, when there is a saturation current, the plate resistance (rp), is (A) zero (B) infinite quantity (C) data insufficient (D) some finite quantity

Tardigrade Admin · Accepted Answer

Plate resistance (rp)=(δ V/δ I) (where dV is the change in voltage and δI is the change in current. At saturation, curreInt δI = 0 . Therefore at saturation (rp)=(δ V/0)=∞.

Q. In a diode, when there is a saturation current, the plate resistance $(r_{p})$ , is

zero

infinite quantity

data insufficient

some finite quantity

Plate resistance $(r_{p}) = \frac{δ V}{δ I}$
(where $d V$ is the change in voltage and
$δ$ I is the change in current.
At saturation, curreInt $δ$ I = 0 . Therefore at saturation
$(r_{p}) = \frac{δ V}{0} = \infty$ .
