How electrical energy is stored?

There are two types of electric power. AC and DC. However, AC (Alternating Current), power cannot be stored. But DC (Direct Current), power can be stored. It is stored in Battery.

There are many types of batteries. The majority of batteries are based on the principle that chemical energy can be converted to electrical energy, satisfying the principle conservation of energy.

AC power cannot be stored. It is like a flow. AC power can be further divided into two types: 1) Active Power and 2) Reactive Power

Active Power is responsible to do real work. Reactive power is responsible for capacitance and inductance.
