Q. A resistor is operated at a temperature of 300 K, with a system bandwidth of 1 MHz then the noise power produced by the resistor is:

  • (A) 3.13×10-23 watts
  • (B) 4.14×10-15 watts
  • (C) 6.14×10-15 watts
  • (D) none of the mentioned

Explanation by: Admin

for a resistor noise power produced is given by ktb, where t is the system temperature and b is the bandwidth. substituting in the above expression, the noise power produced is 4.14×10-15 watts.
