In a system an input resistance of 20 kΩ causes a noise voltage of 15μV. If two such input resistances each of 20 kΩ are used in parallel, the total noise voltage will be about-A-15 μVB-30 μVC-7.5 μVD-10.6 μV-D-10.6 μV

Question

In a system an input resistance of 20 k&Omega; causes a noise voltage of 15&mu;V. If two such input resistances each of 20 k&Omega; are used in parallel, the total noise voltage will be about-A-15 &mu;VB-30 &mu;VC-7.5 &mu;VD-10.6 &mu;V-D-10.6 &mu;V

APTITUDE CRACK · Accepted Answer

D 10.6 &mu;V  Overall resistance = 10 kW. Noise voltage = (15) = 10.6 μV.
