Assertion (A) : Eventhough forward bias is known to be more (mA) than the current in the reverse bias (mu A), photodiodes are still used in reverse bias. Reason ( R) : The fractional change in majority charge carriers woulb be much less than that in minority charge carriers due to photo-effects so that minority carrier reverse bias current is more easily to measure with photo diodes than majority carrier forward current.
