Home electricity is delivered as alternating current (AC), while most electronic devices operate on direct current (DC). This necessitates the conversion of AC to DC for usability. Historically, Thomas Edison advocated for DC systems, while Nikola Tesla supported AC. The flow of electricity is the movement of electrons through conductors, with voltage differences driving the current. AC systems create challenges due to the oscillation of voltage, whereas DC systems, being simpler, can be easily created with a battery and wire.
The electricity that comes out of your wall socket is alternating current, while all the new electronic devices in homes require DC power, leading to conversion needs.
Electricity is a flow of electrons through a conducting material; the electrical grid resembles rivers with current flowing through them driven by voltage differences.
