Why the unit of potential difference and electromotive force is the same?
Because an electromotive force is a potential difference (voltage) -specifically, an electromotive force is the open-circuit or no-load potential difference of a source such as a battery or generator.
Why it is not correct to say that potential difference is the work done in moving unit charge between the point concerned?
Voltage is defined as potential difference (units of volts). Work is equivalent to power (over time), and its' unit is joules. Power is equivalent to the potential difference times the current flow. Without current flow, there is no power, so it is incorrect to define potential difference as work. What I think you're implying is potential energy and potential difference are the same: Potential energy of a rock can be increased by raising the rock into the air. The increase of potential energy of the rock is equivalent to the real work done to raise it higher into the air. This is a true statement. Potential energy (joules) and potential difference (volts) are not equivalent, though, since potential differenence is not defined as work.
Potential difference is measured in a unit called 1 a volt 2 a Watt 3 an Ampere 4 an ohm?
The answer is volt.
Why calculate 22kv in mva?
A kilovolt (kV, not 'kv') is the SI unit for potential and potential difference (voltage), whereas the kilovolt ampere (kV.A, not'kva') is the unit for apparent power. These are quite different quantities, so you cannot change one to another -if that is what you are asking.
How can you get the largest voltage difference?
There is no such thing as a 'voltage difference'! 'Voltage' means 'potential difference', so what you appear to be asking is "How do you get the largest potential difference difference?'! Potential difference is caused by the separation of charges between two points. The greater the amount of charge separation, the greater the potential difference.
The unit of potential difference?
the Volt
What is the electrical unit of potential difference?
The electrical unit of potential difference is the volt, represented by the symbol V. It is a measure of the force that pushes electric charge through a circuit.
What is the difference between electrical potential energy and potential difference?
Electric potential is the electric potential energy per unit coulomb. So unit for electric potential is J/C and that of electric potential energy is simply J
What is the measurement unit of potential difference?
Volt
The volt is the unit of electric?
Yes, the volt is the unit of electric potential or electromotive force. It represents the amount of potential energy per unit charge.
What is the si unit for potential energy difference?
Potential energy is measure in Joules (J). A Joule is a Newton*meter (N*m)
What is potencial difference measured in?
The unit of measure is the Volt Potential difference is basically electrical "pressure" (an excess of electrons). Volt.....The unit of electric potential. Named after the Italian physicist Alessandro Volta (1745- 1827). The potential difference is the difference in charge at the poles of a current source The volt (symbol: V) is the SI derived unit of electromotive force, commonly called "voltage". It is also the unit for the related but slightly different quantity electric potential difference (also called "electrostatic potential difference"). ... en.wikipedia.org/wiki/Volt
What the unit of measure that expresses potential different between two electrodes in a battery?
Volt
The unit to measure current is the volt?
The unit of current is the ampere. The unit of potential difference, or electromagnetic force is the volt.
Why the unit of potential difference and electromotive force is the same?
Because an electromotive force is a potential difference (voltage) -specifically, an electromotive force is the open-circuit or no-load potential difference of a source such as a battery or generator.
What is the potential difference between two spherical shells?
The potential difference between two spherical shells is the difference in electric potential energy per unit charge between the two shells. It is a measure of the work required to move a unit positive charge from one shell to the other.
What is the dimension of potential difference?
The dimension of potential difference is voltage, which is measured in volts (V). Voltage represents the difference in electric potential energy per unit charge between two points in an electric circuit.
