An ideal opamp is said to have infinite gain and high input resistance.
But why do the designers want to have infinite gain? This makes it impossible to use it as differential amplifier as even small voltages will have very large values. We have to add a negative feedback to use the opamp properly
why can't they just design the opamp with lesser gain so that's its easier to use without any feedback
