# Formula: Electrical Energy Voltage    Electric current    Time

## Electrical energy

Unit
Electrical energy that a charge carrier gains or loses when it traverses the voltage $$U$$. A positive charge moving parallel to the electric field lines would gain energy, while a positive charge moving antiparallel to the field lines would lose the energy.

## Voltage

Unit
The electrical voltage indicates how large the potential difference between two points is. Thus, the voltage indicates how much energy a charge carrier gains or loses when it travels the path between two points.

## Electric current

Unit
Electric current is the charge transported within a certain time due to the applied voltage.

## Time

Unit
Time within which the current $$I$$ has flowed.
