Q. The plate characteristic curve of a diode in space charge limited region is as shown in the figure. The slope of curve at point $P$ is $5.0\ mA/V$. The static plate resistance of diode will be
A) 111.1$\Omega$
B) 222.2$\Omega$
C) 333.3$\Omega$
D) 444.4$\Omega$
Explanation
(c) $R_{p} = \frac{V_{p}}{i_{p}} = \frac{50}{150 \times 10^{- 3}} = 333.3\ \Omega$
