Question: Explain how thermal noise power varies ( a ) with temperature and ( b ) with frequency bandwidth. Thermal noise from a resistor is measured

Explain how thermal noise power varies (a) with temperature and (b) with frequency
bandwidth. Thermal noise from a resistor is measured as 410-17 W for a given bandwidth
and at a temperature of 20C. What will the noise power be when the temperature is
changed to (c)50C; (d)70 K?
