Question

a dielectric constant for air is....​

Answer 1

Answer:

The value of the dielectric constant at room temperature (25° C, or 77° F) is 1.00059 for air, 2.25 for paraffin, 78.2 for water, and about 2,000 for barium titanate (BaTiO3) when the electric field is applied perpendicularly to the principal axis of the crystal

Answer 2

Explanation:

Dielectric breakdown occurs when a charge buildup exceeds the electrical limit or dielectric strength of a material. The dielectric strength of air is approximately 3 kV/mm. Its exact value varies with the shape and size of the electrodes and increases with the pressure of the air.
