It is legal to look for work while visiting Canada. Obviously, you should always tell the truth to the officer and state your purposes in the country. You would also need to prove to the immigration officer that the plan is to leave Canada within the maximum allowed time and that you will not work in the country without the proper work permit.
Dielectric materials for semiconductor chips. Dielectric material characterize with very low electrical conductivity (one millionth of a mho / cm), in which an electric field can be sustained with a minimal leakage. It can store electrical energy/charge.
'Electrically Conductive' means the ability of any material or object to conduct electricity through it with offering least possible resistance to the flow of electrons. Silver is found to be the most conductive material of all. That is the reason why it is frequently used in majority of the electrical components and thus resulting in hiking in their prices. Apart from silver; copper, gold & aluminium are also good conductors of electricity as they are having free electrons available for conduction.
