In the circuit a current of no more tha 20 mA may flow for a maximum instataneous voltage of 20 v.In the conducting state direction the voltage drop across each diode is at least 1.5 v.
How large must the protective resistor be?calculate using ohms law.
Question 3: If we assume the reverse current is -99 pA, the built-in voltage is 0.64 V,
and the applied voltage Va is -26 V, what reverse R-G current in pA would we expect if
the applied voltage Va is changed to -1 V. This is for an abrupt junction silicon diode at
room temperature. Answer should be to three significant digits with fixed point notation.
Correct Answer: -24.6
