Common Data Questions: 48 & 49

The channel resistance of an N-channel JFET shown in the figure below is 600$\Omega$
when the full channel thickness (tch) of 10μm is available for conduction. The
built-in voltage of the gate P+ N junction (Vbi) is -1 V. When the gate to source
voltage (VGS) is 0 V, the channel is depleted by 1μm on each side due to the builtin
voltage and hence the thickness available for conduction is only 8μm

Q.49 The channel resistance when VGS = 0 V is

(A) 480$\Omega$

(B) 600$\Omega$

(C) 750$\Omega$

(D) 1000$\Omega$
