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
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.
