  1. The value of resistor creating thermal noise is doubled, the noise power generated is therefore—
    1. Halved
    2. Quadrupled
    3. Doubled
    4. Unchanged
Correct Option: D

The noise power is given by expression
Pn = kTB
where,
k = Boltzmann’s constant
T = Temperature
B = Bandwidth
It means thermal noise is independent from the resistor creating thermal noise. Hence alternative (D) is the correct choice.
