Answer:
D) 4 KTRB
Explanation:
It is a well-known relationship that noise voltage increases with higher resistor values according to the Johnson noise equation, erms = √4kTRB, where erms is the rms voltage noise, k is Boltzmann's constant, T is temperature in Kelvin, R is the resistance, and B is the bandwidth.
