dBu and dBV aredecibel units specifically for measuring voltage. Unlike the dB, they are actually units because they can be converted to an actual voltage value. dBu is dB relative to 0.775 volts; such that 0dBu = 0.775 volts. dBV is dB relative to 1.0 volt; such that 0dBV = 1.0 volt...
If the reverse conversion dBu, or dBV to volts is needed, go to the converter at the bottom. ● What is dBu? That has nothing to do with power. A logarithmic voltage ratio with a referencevoltageofV0= 0.7746 volt ≡ 0 dBu ● What is dBV?
dBV or dB(VRMS) (decibel volt, amplitude ratio) — absolute voltage in decibels relative to 1 V, regardless of impedance. The sensitivity of this Shure PG48 microphone is –53.5 dBV/Pa or 2.10 mV/Pa (1 Pa = 94 dB SPL) dBmV or dB(mVRMS) (decibel millivolt, amplitude ratio) — ...
volts (p-p)|volts (p-p)| The origin of the index of dBu comes from "u =unloaded" and dBV comes from "V = 1 volt". Some say: The "u" in dBu implies that the load impedance isunspecified,unterminated, and is likely to be high. ...
The power of this discharge in the electric lighters is so small, that its energy is only enough for heating the gas to its temperature of combustion. Lightning and the Ionosphere The power of single lightning at an average voltage of 20 million volts and a current of 20 thousand amper...
For dBv : 4 = 20 log (E1/ 0.775) => E1= 1.23 volts. For dBV : 4 = 20 log (E1/ 1) => E1= 1.6 volts. dBW As for this type of decibel you probably guess correctly again, it has a power related reference. Just like dBm, but the only difference is the wattage reference. Sin...
U is the potential difference or voltage between the ends of the conductor, measured in volts (V); I is the electric current that runs between the ends of the conductor, measured in amperes (A). This formula is known as Ohm’s law, named after the German physicist who discovered it. ...

The power of single lightning at an average voltage of 20 million volts and a current of 20 thousand amperes can be about 200 million kilowatts. This number takes into account the fact that when lightning strikes, the voltage drops from the maximum value to zero. One large thunderstorm produc...
