Definitions:

Charge Rate

Charge rate denotes the speed at which a battery or capacitive device is charged, typically measured in amperes or a relative percentage per hour.

Exponential

The rate at which current rises and falls in inductor or the rate at which capacitors charge and discharge.

Dielectric Stress

The electric stress or field strength within an insulating material, which can lead to breakdown if it exceeds the material's dielectric strength.

Voltage Difference

The difference in electric potential between two points in an electric circuit, driving the flow of current.
