WebThe voltage across R B1 is V a = V BB * (R B1) / (R B1 + R B2) The ratio R B1 / (R B1 + R B2) is called intrinsic standoff ratio h = R B1 / (R B1 + R B2) i.e. V a = h V BB. The ratio h is a property of UJT and it is always less than one and usually between 0.4 and 0.85. As long as I B = 0, the circuit of behaves as a voltage divider.
