Detailed explanation-1: -The strength of the electric field is measured in volts per meter and varies with the amount of the source voltage. The higher the source voltage, the higher the strength of the field. Electric field strength decreases rapidly with distance from the source.

Detailed explanation-2: -Dielectric strength is measured as the maximum voltage required to produce a dielectric breakdown through a material. It is expressed as Volts per unit thickness. For a plastic material the dielectric strength varies from 1 to 1000 MV/m. Higher dielectric strength corresponds to better insulation properties.

Detailed explanation-3: -Voltage is the pressure from an electrical circuit’s power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light. In brief, voltage = pressure, and it is measured in volts (V).

Detailed explanation-4: -Electric strength is the maximum voltage that an insulating material can take, after which it loses its insulating properties. The value obtained for the electric strength will depend on the thickness of the insulating material and on the method and conditions of test.

Detailed explanation-5: -The voltage is commonly referred to as the electric potential difference and can be measured using a voltmeter. The electrical potential difference between the two plates is expressed as V = E d, the electric field strength times the distance between the plates.
