What Is Electrical Energy
What Is Electrical Energy?
Definition: The energy which is caused by the movement of the electrons from one place to another such type of energy is called electrical energy. In other words, electrical energy is the work done by the moving streams of the electrons or charges. Electrical energy is the form of kinetic energy because it produces by the movement of the electrical charges. The faster the movement of charges the more the energy they carry.
Considered a circuit shown in the figure below. When a potential difference P is applied across the circuit a current (I amperes) flow through it for a particular period t seconds. The voltage applied across the circuit is equal to the ratio of the work done by the electrical charge to the number of electrical charges present in the circuit. It is expressed by the formula shown below.
Therefore work done or electrical energy expanded
Unit of Electrical Energy
Basically, we find the unit of electrical energy is joule. This equals to one watt X one second. Commercially, we also use other units of electrical energy, such as watt-hours, kilo watt hours, megawatt hours etc.
Watt Hours
If one watt power is being consumed for 1 hour time, the energy consumed is one watt-hour.
