Frequency za Wasafi FM Tanzania: Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around 20 kHz to around 300 GHz.

This is roughly between the upper limit of audio frequencies and the lower limit of infrared frequencies; these are the frequencies at which energy from an oscillating current can radiate off a conductor into space as radio waves Frequency za Wasafi FM Tanzania. Different sources specify different upper and lower bounds for the frequency range.

Electric currents that oscillate at radio frequencies (RF currents) have special properties not shared by direct current or lower audio frequency alternating current, such as the 50 or 60 Hz current used in electrical power distribution.

Energy from RF currents in conductors can radiate into space as electromagnetic waves (radio waves). This is the basis of radio technology.

RF current does not penetrate deeply into electrical conductors but tends to flow along their surfaces; this is known as the skin effect of Frequency za Wasafi FM Tanzania.

RF currents applied to the body often do not cause the painful sensation and muscular contraction of electric shock that lower frequency currents produce. This is because the current changes direction too quickly to trigger depolarization of nerve membranes. However this does not mean RF currents are harmless; they can cause internal injury as well as serious superficial burns called RF burns.

RF current can easily ionize air, creating a conductive path through it. This property is exploited by “high frequency” units used in electric arc welding, which use currents at higher frequencies than power distribution uses Frequency za Wasafi FM Tanzania.
