GATE EE 2025 Question Paper (02-Feb-2025) (Shift-2)

The op-amps in the following circuit are ideal. The voltage gain of the circuit is _________ . (Round off to the nearest integer)

The switch (S) closes at $t=0$ sec. The time, in sec the capacitor takes to charge to 50 V is _______. (Round off to one decimal places)

In an experiment to measure the active power drawn by a single-phase RL Load connected to an AC source through a 2 $\Omega$ resistor, three voltmeters are connected as shown in the figure below. The voltmeter readings are as follows : $V_{\text{source}}=200$ V, $V_R=9$ V, $V_{\text{Load}}=199$ V. Assuming perfect resistors and ideal voltmeters, the Load-active power measured in this experiment, in W, is _______.

In the Wheatstone bridge shown below, the sensitivity of the bridge in terms of change in balancing voltage $E$ for unit change in the resistance $R$, in mV/$\Omega$, is _______. (round off to two decimal places)

The steady state capacitor current of a conventional DC-DC buck converter, working in CCM, is shown in one switching cycle. If the input voltage is 30 V, the value of the inductor sued, in mH, is _______ (round off to one decimal place).
