Q. In the circuit shown below, the op-amp is ideal and Zener voltage of the diode is 2.5 volts. At the input, unit step voltage is applied, i.e. π£πΌπ(π‘) = π’(π‘) volts. . Also, at π‘ = 0, the voltage across each of the capacitors is zero.
The time π‘, in milliseconds, at which the output voltage π£πππ crosses β10 V is
(A) 2.5 (B) 5 (C) 7.5 (D) 10
Ans: 7.5
