Answer Posted / ranveer kumar

according to my idea active elements are those device or
element which is capable to amplify or modify,and itself
have ability to generate energy such devices are
ujt,transistors,fets
but passive have not ability to generate energy itself
these are inductors,resistors,and capacitors ;by using
these we can generate energy;
now we can say clearly active element have
amplification ,modification ,transversion property but
passive while consuminng property
