supercapacitor

Example:Batteries have a higher energy density than supercapacitors but are slower to charge and discharge.

Definition:A device consisting of one or more electrochemical cells that convert stored chemical energy into electrical energy that can be used to power electrical devices.

Example:A resistor is used to control the flow of electric current in a circuit, unlike a supercapacitor that stores and supplies electrical energy.

Definition:A passive two-terminal electrical component that implements electrical resistance as a circuit element.
