Question

________ has high dialectric constant ​

Answer 1

Answer:

Water

Explanation:

Water has a high dielectric constant because the water molecule have dipole moment and so it can be polarized. Under a given electric field, water tends to polarize strongly, nearly canceling out the effect of the field.

Answer 2

Answer:

$\huge\bf\red{water}$

Explanation:

Water has a high dielectric constant due to strong bonds between hydrogen and oxygen as well as hydrogen bonding between water molecules. Water also doesn't ionize so even it has strong charges those charges are tightly bound to the molecule.
