Assertion (A): In a two-transistor model the anode current is given by: ${I_A} = \frac{{{\alpha _2}{I_G} + {I_{CB{O_1}}} - {I_{CB{O_2}}}}}{{I + \left( {{\alpha _1} - {\alpha _2}} \right)}}$Reason (R): The regenerative or Latching action due to positive feedback is demonstrated in a two-transistor model of a thyristor. It contains a pnp & a npn transistors.
