What to Focus On
- Electric potential is a scalar quantity measured in volts.
- Potential difference is the work done per unit charge.
- The electric field is the negative potential gradient.
- Potential due to a point charge is inversely proportional to distance.
- Potential due to a dipole is inversely proportional to the square of the distance.
- On the equatorial line of a dipole, the potential is zero.
- Potential energy is the work done to assemble charges.
- Like charges have positive potential energy; unlike charges have negative.
- Dipole in an electric field has minimum energy when aligned with the field.
Common Mistakes to Avoid
Electric potential is a vector quantity like electric field, so it has direction.
If electric field is zero at a point, electric potential must also be zero there.
Potential energy of a charge system is always positive.
Memory Tips
Electric potential is work done per unit charge to bring a test charge from infinity to a point
Potential due to a point charge: V = (1/4πε₀)(q/r)
Potential due to dipole on axial line: V = (p cosθ)/(4πε₀r²)
On equatorial line, electric potential due to dipole is zero
