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.
Capacitor stores energy in electric field. The stored energy is not maintained indefinitely, as the dielectric present between the plates allows for a certain amount of current leakage which results in the gradual dissipation of the stored energy....
