Before firing, the voltage from anode to the cathode is a. OV If the gate is made on. a. Negative The SCR will biased. b. Approximately Equal to Vcc. when the anode and cathode are forward-biased, the SCR turns a. b. Positive when the gate potential is removed and the anode/cathode are forward- a. Remain on b. Turn off When the SCR is off, the voltage from the anode to ground is Close to VCC b. Near 0 The SCR will turn off when the current flowing through it drops below the value.
