What are polar molecules
Polar molecules - molecules having of two or more atoms that are neutral but have a charge which is not distributed uniformly.
The electric field strength, defined as a force per unit charge, has the units Newton per coulomb, N/C. The formula for electric potential difference, ΔV = Ed, though, suggest
