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 if v + > v - V 0 = - 10 V if v + < v - The output V 0 of this circuit a long time after it is switched on is best represented by

Correct answer

0

Step-by-step solution

V 0 can only have two values either + 10 or - 10 ∴ Only (A) is possible
