List of top Physics Questions on Electronics

In the circuit shown, \(V(t) = 2\sin(2000\pi t)\) Volts, where \(t\) is in seconds. The source \(V(t)\) drives the non-inverting (+) input of an opamp directly, the inverting (-) input is tied to ground (0 V), and the opamp is powered from +15 V and -15 V rails with no feedback network between its output and either input. Take the opamp to be ideal. Which of the following options is correct?
Considering the circuit and the associated signals measured at different pins (numbered as 1, 2, 3, 4, 5) shown in the figure, the correct option is
