In multisim Before firing, the voltage from anode to the cathode is ___________.a. 0 V b. Approximately Equal to VCCIf the gate is made _______ when the anode and cathode are forward-biased, the SCR turns on.a. Negative b. PositiveThe SCR will _______ when the gate potential is removed and the anode/cathode are forward-biased.a. Remain on b. Turn offWhen the SCR is off, the voltage from the anode to ground is ________.a. Close to VCC b. Near 0The SCR will turn off when the current flowing through it drops below the __________ value.

these are the questions on basic properties of a SCR1) Approximately Equal to Vcc before firing the SCR/diode will be turn off i.e open circuit hence the voltage across open circuit is supply itself hence Before firing, the voltage from anode to the cathode is Approximately Equal to Vcc. 2)POSITIVE to turn on the scr the anode and cathode are made forward bias and gate supply should be positive 3)remain on once the SCR is turn on even if gate voltage is removed the SCR will be in on condition untill the anode cathode are forward biased(if anode cathode are negative biased or supply removed then SCR will turn off) 4)close to Vcc when SCR is turn off it behaves as open circuit hence voltage across it same as Vcc since anode is connected to positive potential and cathode is connected to negative potential/ground the voltage across anode and ground is close to Vcc 5)HOLDING CURRENT if anode current is made less than holding current then the SCR will turn off
