Vooluallikaid
Vooluallikaid refers to sources of electric current. In physics and electrical engineering, a vooluallikas is a device that provides a voltage difference and can deliver electrical energy to a circuit. These sources are fundamental to the operation of all electrical and electronic devices.
There are two main categories of vooluallikaid: direct current (DC) sources and alternating current (AC) sources.
The characteristics of a vooluallikas are often described by its voltage, which is the electric potential difference
