An amplifier has an input resistance of 10 kΩ and the noise voltage is 10 μV. If two such resistances of 10 kΩ each are connected in series at the input, the total noise voltage is about-A-20 μVB-5μVC-14.14 μVD-10 μV-C-14.14 μV

Question

An amplifier has an input resistance of 10 k&Omega; and the noise voltage is 10 &mu;V. If two such resistances of 10 k&Omega; each are connected in series at the input, the total noise voltage is about-A-20 &mu;VB-5&mu;VC-14.14 &mu;VD-10 &mu;V-C-14.14 &mu;V

APTITUDE CRACK · Accepted Answer

C 14.14 &mu;V  Noise voltage = 10 = 14.14 μV.
