Answer Posted / a.p

the thyristor will conduct in the forward direction and in
the reverse direction, it will show reverse recovery
voltage, thus a high resistance. Or we may put a diode in
parellel with the thyristor. The current gets diveded when
the thyristor is conducting. Else all the current flows
through the diode alone. In this way the thyristor could be
checkd.
