GATE IN 2014 Question Paper (02-Feb-2014) (Shift 2)

Semiconductor strain gages typically have much higher gage factors than those of metallic strain gages, primarily due to :

For a rotameter, which one of the following statements is TRUE?

1 for the op-amp shown in the figure, the bias currents are I${}_{b1}$ = 450 nA and I${}_{b2}$ = 350 nA. The values of the input bias current (*I${}_B$)and the input offset current (I${}_f$)* are

The amplifier in the figure has gain of -10 and input resistance of 50 kΩ. The values of Rᵢ and *R${}_f$ * are

For the circuit shown in the figure assume ideal diodes with zero forward resistance and zero forward voltage drop. The current through the diode D₂ in mA is ___________.
