Respuesta :

The energy of a body is its capacity to do work.
The SI unit of energy is joule (J) and the CGS unit of energy is erg, where 1 J = 10raise to 7 erg.
The bigger units of energy are watt hour (Wh) and kilowatt hour (kWh).

The units that can be used to express electrical energy is :

Volt, ampere and seconds ( i.e. volt*ampere*seconds )

Electrical energy is power contained in a charged particle that results in an action been carried out. it is generated by the movement of electrons between atoms.

The S.I unit of electrical energy is Joule and 1 Joule is can be calculated as:

1 Joule = 1 voltage * 1 current * time ( in seconds )

            = 1 Volt * 1 ampere * 1 second

hence the combination of units that can be used to express electrical energy aside its' S I unit ( Joule ) is ;  volt*ampere*seconds
