Referring to Figure below: (Assume values of VBE = VCE(sat) = 0.7 for both device) Given: Vin = 45 V, R₁ = 10 kN, RB + Rc = 10 k a. Assuming the Shockley diode reached its breakover voltage and now is in on- state, determine the minimum resistance of the potentiometer (Rc) necessary to turn on the SCR if it requires a 3mA triggering current. b. Determine the gate current when the resistor Rc is adjusted to its maximum value, assuming all devices are turned on.
