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

💬 Discuss

✅ Correct Answer: (B) 4.14×10-15 watts

Explanation: 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.
