Final answer:
The statement is true; a dielectric material indeed has a high resistance to current at low voltages. Dielectric strength is the point where the insulating properties are lost and the material conducts electricity.
Step-by-step explanation:
The statement "A dielectric material has a very high resistance to current when a low voltage is applied to it" is true.
A dielectric material is an insulating material designed to have a high resistance to the flow of electric current. It retains this characteristic at low voltages, which is the main reason dielectric materials are used in applications requiring insulation from electrical charges. However, once the voltage reaches a certain threshold - known as the dielectric strength - the dielectric material can break down and begin to conduct electricity, thus losing its insulating properties. Specifically, dielectric strength is defined as the maximum electric field strength above which an insulating material cannot maintain its electrical insulating properties and begins to break down and conduct.
