Insulator cannot store charge but die electric can (Like capacitor). we can refer all die electrics are insulator but not all insulators are die electrics. insulator allows very less amount of current which doesn't show affect on circuit, but die electric can pass the electrons through it if it is excited by a source.

Answer / er. sanjana singh

Di-electric has capability to storage charge.it is also a insulator but when it is exited by a source it pass storage energy.
insulator is a substance which does not allow to flow current through it...

why they charge more bill for low power factor rather than high power factor
