Marks: +1, -0

The box in the circuit below has two inputs marked

{v}_{+}

and

{v}_{-}

and a single output marked

{V}_{0} .

The output obeys

+10 {V}

{v}_{+}>{v}_{-}

V_0=-10 {V}

{v}_{+}<{v}_{-}

The output

{V}_{0}

of this circuit a long time after it is switched on is best represented by

Solution:

{V}_{0}

can only have two values either

+10

-10

\∴

Only (A) is possible
