When checking a good SCR or TRIAC with an ohmmeter it will:
show high resistance in both directions
show low resistance with positive on anode and negative on cathode, and high resistance when reversed
show high resistance with negative on anode and positive on cathode, and low resistance when reversed
show low resistance in both directions
Answer: Option
Explanation:
No answer description is available. Let's discuss.

Because the SCR can only be turned on by surpassing the forward breakover voltage the ohmmeter cannot supply enough voltage to turn it on this it would have a high resistance in both directions indicating that it is good and working properly.

Please explain the correct answer.

It will show on ohmmeter like as open cct.

The answer is B why means their will be an low resistance in the forward bias and high resistance in the reverse bias.

The SCR acts like a very high-resistance rectifier in both forward and reverse directions without requiring a gate signal.

Could any one explain how the answer will be A
