GATE EE 2021 Question Paper (07-Feb-2021) (Shift 1)

Two generators have cost functions F₁ and F₂. Their incremental-cost characteristics are

$\frac{d{F}_1}{d{P}_1}=40+0.2P_1$

$\frac{d{F}_2}{d{P}_2}=32+0.4P_2$

They need to deliver a combined load of 260 MW. Ignoring network losses, for economic operation, the generations P₁ and P₂ (in MW) are

Consider the boost converter shown. Switch Q operating at 25 kHz with a duty cycle of 0.6. Assume the diode and switch to be ideal. Under steady-state condition, the average resistance Rᵢₙ as seen by source is ______ Ω. (Round off to 2 decimal places.)

A CMOS Schmitt-trigger inverter has a low output level of 0 V and a high output level of 5 V. It has input thresholds of 1.6 V and 2.4 V. The input capacitance and output resistance of the Schmitt-trigger are negligible. The frequency of the oscillator shown is ______ Hz. (Round off to 2 decimal places.)

Consider the table given:The correct combination that relates the constructional feature, machine type and mitigation is

A three-phase balanced voltage is applied to the load shown. The phase sequence is RYB. The ratio $\frac{|I_B|}{|I_R|}$ is ______.
