Question

what is the meaning of"water has a high dielectric constant"

Answer 1

Dear Student,

Dielectric constant is the ratio of the permittivity of the substance to the permittivity of the free space.
Water has a high dielectric constant due to strong bonds between hydrogen and oxygen as well as hydrogen bonding between water molecules.
Hence water has a high dielectric constant means that the ratio of permittivity of water with respect to free space (air) is high due to the above reason.
