Solution

The correct option is B 1 v

An op amp has an offset voltage of 1 mv and is ideal in all others respects. If this op amp is used in the circuit, the output voltage will be 1v.

The integrator Op-amp produces an output voltage that is both proportional to the amplitude and duration of the input signal.

Operational amplifiers can be used as part of a positive or negative feedback amplifier or as an adder or subtract or type circuit using just pure resistances in both the input and the feedback loop.
