Online TestThyristors Questions and Answers – Part 1 Thyristor Questions and Answers Power Electronics Objective Questions & Answers 0% Choose the false statement. In SCR the gate is the controlling terminal SCR are used for high-power applications SCR is a bidirectional device SCR is a controlled device Correct!Wrong!- Continue >> Which terminal does not belong to the SCR? Anode Cathode Base Gate Correct!Wrong!- Continue >> The static V-I curve for the SCR is plotted for Ig vs Vg with Ia as a parameter Va vs Ig with Ia as a parameter Ia (anode current) vs Ig (gate current), Va (anode – cathode voltage) as a parameter Ia vs Va with Ig as a parameter Correct!Wrong!- Continue >> In the SCR structure the gate terminal is located in between the anode & cathode terminal none of the mentioned near the cathode terminal near the anode terminal Correct!Wrong!- Continue >> A thyristor (SCR) is a P-N-P device P-N device P-N-P-N device N-P-N device Correct!Wrong!- Continue >> If the cathode of an SCR is made positive with respect to the anode & no gate current is applied then all the junctions are forward biased only the middle junction is reversed biased only the middle junction is forward biased all the junctions are reversed biased Correct!Wrong!- Continue >> An SCR is a four layer, four junction device four layer, three junction device four layer, two junction device three layer, single junction device Correct!Wrong!- Continue >> For an SCR in the forward blocking mode (practically) leakage current flows from gate to anode leakage current does not flow leakage current flows from anode to cathode leakage current flows from cathode to anode Correct!Wrong!- Continue >> With the anode positive with respect to the cathode & the gate circuit open, the SCR is said to be in the forward conduction mode reverse blocking mode forward blocking mode reverse conduction mode Correct!Wrong!- Continue >> For an SCR in the reverse blocking mode, (practically) leakage current flows from cathode to anode leakage current does not flow leakage current flows from gate to anode leakage current flows from anode to cathode Correct!Wrong!- Continue >> Share the quiz to show your results !
