Supercapacitors

Capacitance is measured in

• Metre

• Farad (F)

• volts (V)

• Ampere

If the thickness of the plate increase, Capacitance

• decrease

• not change

• increase

• double

Relative” permittivity of glass

• 1

• 3

• 7

• 0

Energy is stored in ultra capacitor

• by polarizing the electrolytic solution

• by redox reaction

• both

• by deposition of ions

In Pseudo-capacitors charge stored by

• Electrochemically

• Electrostatically

• both

• by deposition

In Doublelayersupercapacitors charge stored by
