Napětí

Napětí (in English „voltage“) refers to the electric potential difference between two points in an electrical circuit. It is a measure of the work done per unit charge to move a charge from one point to another. Napětí is typically measured in volts (V) and is a fundamental concept in the field of electronics and electrical engineering. It determines the potential for current to flow in a circuit; higher voltage generally means a greater potential for current to move. Napětí can exist in various forms, including direct current (DC) and alternating current (AC), and plays a crucial role in powering electrical devices and systems. In essence, napětí is essential for understanding how electric circuits operate and is a key factor in the analysis and design of electronic components.
