Answer Posted / kedas
as v know dat the input impedance of the opamp is ideally infinite.basically it means impedance between inverting and non-inverting terminals is very high.by this v can say that internally current passage between the terminals is ideally zero.basic concept here is current between two equal voltages is zero.using dis v can say dat voltages at two terminals are equalbcz current is zero.this is called virtual short.if any one terminal is grounded the other terminal is also grounded.simple very easy concept!!!!!!!!!!!!!!!!!!hope it helps:)
