What unit measures EMF?
EMF stands for Electro-Motive Force, commonly known as Voltage, measured in Volts.
How do you get -12 decibels?
Decibel is a factor or a ratio and no unit. If you have 1 volt and you damp it to 1/4 volt then you will get a damping of 12 dB. Voltage daming = 20×log (1/4) = (-)12 dB.
What is the conversion between N-m to eV and vice-versa?
A Newton*Meter (N·m) is a Joule (J) and a Joule is the derived unit of energy in SI units. N=(kg*m/s^2) so a N·m=(kg*m^2/s^2)=J. An electron volt is also a quantity of energy equal to approximately 1.602×10−19 J. Correspondingly, one joule equals 6.24150974×1018 eV. By definition, it is equal to the amount of kinetic energy gained by a single unbound electron when it accelerates through an electric potential difference of one volt. Thus it is 1 volt (1 joule per coulomb) multiplied by the electron charge (1 e, or 1.60217653(14)×10−19 C). Therefore, one electron volt is equal to 1.60217653(14)×10−19 J. The electron volt is not an SI unit and its value is derived from knowing the charge of the electron. To change Js to eV divide by the charge of an electron 1.602x10-19 C. To change eVs to Js multiply by the charge of an electron 1.602x10-19 C.
What 1mv in decimal equation?
1 millivolt = 0.001 volt
Is 1 6 equal to 1 3?
2 sixths are equal to 1 third
The unit of emf is?
the unit of "e.m.f" is "volt"
What is an electric volt?
Volt is the unit of voltage.One volt is equal to 1 joule per coulomb:1 V = 1 J/C
What is electric volt?
Volt is the unit of voltage.One volt is equal to 1 joule per coulomb:1 V = 1 J/C
What are the differences between potential difference and emf?
emf is present mainly in battery and potential difference is mainly present in circuit. emf is greater than p.d and p.d is greater than emf.......the units of both are Volt.....
What will the emf of battery if 2ohms and 3ohms are connected in series and a 5 ampere cureent is passing through the circuit connected?
1 volt
Unit of measurement for electromotive force?
emf has SI units of volts, equivalent to joules per coulomb.
If an EMF of 1 volt causes a current of 1 ampere what is the resistance of the material through which the current is flowing?
1/1 = 1ohm MR. volta [italian] Determined that it would take 1 volt to pass 1 amp trough a 1 ohm resistor MR ampere [ french] Ditermined that it would take 1 ohm and 1 volt to pass one ampere MR ohms [english] determinaed that for 1 volt and one ampere the resistance must be 1 ohm. mr watts determined that the product of volts x ampere will equal one watt [power]
What unit would be used to measure the potential difference between two poles of a battery?
The volt.The volt.The volt.The volt.
What is a unit used to measure resistance?
The " Ohm " is. 1 ohm is the resistance across which 1 volt of EMF appears when the current through it is 1 Ampere.
A cell of emf E volt and its internal resistance is 'r' ohm. The cell is connected to a load of 'R' ohm. The potential difference across the terminals of the cell is?
The resistance is equally proportionate to "r" in the case that it is above 1. Assuming "r" is greater than 1, the resistance is 4/3 multiplied by omega (the equal proportionate value for mass times ohms). If "r" is less than or equal to 1, there is no resistance.
What is the basic metric measurement unit that is equal to 1 Volt Amperes?
1 volt x 1 ampere = 1 watt, a unit of power. One watt is also the same as one joule / second.
How many amps is equal to 1 kilo volt amp?
A volt-amp or VA is equivalent to watts, provided the voltage and amperage are in phase. So 1 kilo volt amp is the same as 1 kilowatt. Wattage, or power, is equal to volts times amps. So the original question is effectively nonsense. The number of amps depends on the voltage. If the voltage is 1000 volts, then there's 1 amp in 1 kilo volt amp. If the voltage is 1 volt, then there's 1000 amps. If there's 50 volts, then the amperage is 20 amps. And so on.
