Why is short circuit should touch the dielectric?

A short circuit should touch the dielectric to ensure that the electrical current can flow through the dielectric material, which acts as an insulator between conductive elements. This contact can help prevent electrical arcing or overheating by providing a controlled path for the current. Additionally, the dielectric can help dissipate any generated heat and reduce the risk of damage to the surrounding components. Proper contact ensures that the system operates safely and effectively.
