Thermal noise power in a conductor is proportional to?
Thermal noise is the noise generated by thermal agitation of electrons in a conductor. The noise power "P" in Watts , is given by "P=KTB". The movement or agitation of atoms in conductors and resistors is somewhat random and determined by the temperature of the conductor or resistor. The random movement of electrons is brought about bythermal agitation of the atoms that tends have increased energy as the temperature rises. This random movement gives rise to electrical voltages within the circuitry known as either, thermal noise, resistor noise, Johnson noise or circuit noise. This noise is existent across the frequency spectrum, meaning the more bandwidth occupied the likelihood of greater exposure.Example:K = Boltsmans Constant = 1.3807x10^-23T = Temperature (Kelvin) = 273K + 20 º CB = Bandwidth (Hz) = 180x10^3Noise Power = K x T x B
Do the sun have thermal energy?
Yes.Thermal energy is energy that is derived from heat.
What is the derived unit for thermal energy?
British Thermal Unit, , a unit measurement of heat or energy, usually abbreviated as Btu or BTU. One Btu was originally defined as the quantity of heat required to raise the temperature of 1 lb (0.45 kg) of water from 59.5° F (15.3° C) to 60.5° F (15.8° C) at constant pressure of 1 atmosphere;The SI unit for all forms of energy is the joule: defined as Kilograms meters2/second2Fahrenheit, Celsius, and Kelvin.
A material that conducts thermal energy well is a thermal?
Something that conducts thermal energy well is a thermal...conductor. If it does not conduct well it is called an insulator.
When is thermal produced?
a thermal is produced never

If bandwidth of amplifier reduced then thermal noise in amplifier?
thermal noise willbe reduce
Types of internal noise?
1. Shot or Schottky noise 2. Thermal or Johnson noise 3. Partition noise.
What is the suffix for thermal energy?
The suffix for thermal energy is "ies" as in "energies". The word "thermal" is derived from German. Thus the suffix for thermal is "en" as in "thermalen".
What are the difference between potential energy kinetic energy and thermal energy?
potential energy- is derived chemically from something kinetic energy-is derived from something by the motion the object has thermal energy-is derived by heat or cold

Is thermal energy derived from the wind?
If you refer to the definitions: No. Thermal energy is heat energy. Energy derived from the wind is known as wind energy, also as eolic energy.
The amount of thermal noise is measured by?
Decible(dB)
What factors control the voltage of a Johnson noise source?
It is the bandwidth, the temperature, and the resistance. Look at the link: "Calculation of Noise voltage: Thermal noise".
What are the products derived from the thermal cracking of butane?
c4h10=2c2h4 +h2
Do the sun have thermal energy?
Yes.Thermal energy is energy that is derived from heat.
Why thermal noise is called white noise?
Thermal noise occurs due to the motion of millions of electrons in a object. Due to the central limit theorem, the total effect can be modeled as a Gaussian distributed random variable with zero mean and N_0/2 variance.
