Answer Posted / safi sara
since there are two input terminals in the inputside so the
resistance between the two input terminal is very very
high.so a negligible amount of current flows through op-amp
otherwise the current will be zero,then current only passes
through feedback resistance.hence the input terminal is
assumed to be virtual ground
