Which property of UJT signifies the voltage division factor whose value is always supposed to be less than unity?

Options:

a. Intrinsic Stand-off Ratio
b. Extrinsic Stand-off Ratio
c. Current to Resistance Ratio
d. Voltage to Current Ratio

Correct Answer: a. Intrinsic Stand-off Ratio

Explanation:

Intrinsic stand-off ratio is said to have a value which is always supposed to be less than 1.

This is so because it specifies the voltage division factor which is usually a ratio of base resistances of first transistor to the additional sum of base resistances concerned to another transistor.

Stand-off ratio = Rb1 /(Rb1+ Rb2)

However, it can also be represented in terms of voltage values as,

V_A = stand-off ratio x V_BB

This eventually results in the voltage drop at the base resistance of another (second) transistor.
