Võimsusallikas

Võimsusallikas, often translated as power source or power supply, refers to any device or system that provides electrical energy to an electrical circuit or device. These sources convert some form of energy into electrical energy that can be used to operate other equipment. Common examples include batteries, which store chemical energy and convert it into electrical energy through a chemical reaction, and generators, which convert mechanical energy (often from engines or turbines) into electrical energy via electromagnetic induction.

Other types of võimsusallikas include mains power adapters, which convert alternating current (AC) from the electrical grid into direct current (DC) or a different AC voltage required by electronic devices. Solar panels are photovoltaic devices that convert light energy directly into electricity. Nuclear power plants and hydroelectric dams are large-scale power generation facilities that act as major võimsusallikas for entire regions, utilizing nuclear fission or the kinetic energy of water, respectively. The choice of võimsusallikas depends on factors such as the required power output, portability, availability of fuel or energy source, and cost.
