What is the difference between impact resistance and ...

In direct current (DC) circuits, impact resistance is the term used to describe the manner in which electrical energy is converted into heat. In DC circuits, the resistivity of materials will differ. However, when it comes to AC circuits, the current oscillates as a sine wave which is constantly changing.

Impact resistance decreases with an increase in the modulus of elasticity, which means that stiffer materials will have less impact resistance. Resilient materials will have better impact resistance. Different materials can behave in quite different ways in impact when compared with static loading conditions.
