What to Focus On
- Electric potential is work done per unit positive test charge.
- Its SI unit is volt.
- Electric potential is a scalar quantity.
- Potential difference is work done per unit charge from one point to another.
- A free positive charge moves from higher potential to lower potential.
- A free negative charge moves from lower potential to higher potential.
- Electron-volt is a unit of energy.
- 1 eV = 1.6 × 10^-19 J.
- It is useful in atomic physics.
Common Mistakes to Avoid
Electric potential and electric field intensity are the same thing.
The negative sign in E = -dV/dr can be ignored because it is only a convention.
Potential on the equatorial line of a dipole is zero, so the electric field there is also zero.
