Yield strength is the point at which a material begins to deform permanently, while tensile strength is the maximum stress a material can withstand before breaking.
The formula for calculating the electric field strength between two plates is E V/d, where E is the electric field strength, V is the potential difference between the plates, and d is the distance between the plates.
