Difference between potential due to point charge and dipole
Electric potential is when charges exerts electric force on each other in the system and if we change the position of one or more charges then they will do some work so when we calculate the work done per unit charge is nothing but the electric potential. Electric potential is scalar quantity and its unit is Joules/Coulomb (Volts). Here we are going to discuss about the potential due to point charge and the potential due to dipole. Dipole is nothing but the two charges one is +ve and another is –ve and they are separated by the small distance. A point charge is single charge at a single point in a space. The difference between them is as follows.
Potential due to point charge |
Potential due to dipole |
1) In electric potential due to point charge we are calculating potential of single point at a point in the space which is separated by small distance.
2) Electric potential due to point charge is depend on the distance r. 3) Electric potential due to point charge is given by: V = Q/4πϵ0r |
1) In electric potential due to dipole we are calculating a potential at a point due to two equal and opposite charges separated by the small distance.
2) Electric potential due to dipole is depend on two equal and opposite charge and inclination of r. 3) Electric potential due to dipole is given by: V = p cosϴ/4πϵ0 r2 |
Wow so clear and helpful . Thank you so much
