What is electric potential and its unit?
It is defined as, An electric potential is the amount of work needed to move a unit positive charge from a reference point to a specific point inside the field without producing any acceleration. Its SI unit is j/c=Volts.
Which one of the following is not a unit of electric potential?
Electrostatic potential is electrostatic potential energy gained or lost in moving a unit charge in an electric field. Hence, Joule / Coulomb is also a unit of Electrostatic potential. Option c) Newton/Coulomb : Force per unit charge which is electric field. Hence, option c) is not a unit of electrostatic potential.
What are the units of electric potential difference?
ELECTRIC POTENTIAL DIFFERENCE
Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta. The familiar term voltage is the common name for electric potential difference.
What is potential unit?
The SI unit of potential or potential difference is Volt. One Volt may be defined as the one joule of work-done to move a charge of one coulomb.
Why is electric potential important?
The discussion of electric potential is important because we are always looking for convenient sources of energy. Since any two point charges exert a force of attraction or repulsion on each other, if one charge moves in the field of the other a distance dr under an average force F, the work done is equal to Fdr.
Is J C unit of electric field?
Thus the units of volts are: units of volts, V = joules coulombs = J C .
