GATE EC 2014 Question Paper (15-Feb-2014) (Shift 1)

For maximum power transfer between two cascaded sections of an electrical network, the relationship between the output impedance Z₁ of the first section to the input impedance Z₂ of the second section is

Consider the configuration shown in the figure which is a portion of a larger electrical network



For R = 1 Ω and currents i ₁= 2 A, i ₄= -1 A, i ₅= -4 A. Which one of the following TRUE?

When the optical power incident on a photodiode is 10 μW and the responsivity is 0.8 A/W, the photocurrent generated (in μA ) is

In the figure, assume that the forward voltage drops of the PN diode D₁ and Schottky diode D₂ are 0.7 V and 0.3 V, respectively. If ON denotes conducting state of the diode and OFF denotes a non-conducting state of the diode, then in the circuit.

If fixed positive charges are present in the gate oxide of an n-channel enhancement type MOSFET it will lead to
