What is Voltage?
Voltage, also called electric potential difference, is the difference in electric potential between two points. It represents the work needed to move a unit charge from one point to another.
Common Applications
- • Power systems and electrical grids
- • Electronic circuit design
- • Battery and energy storage systems
- • Motor and generator specifications
- • Safety and protection systems
Safety Levels
Fundamental Concepts
Voltage is a fundamental electrical quantity that drives current through circuits. It's measured in volts (V) and represents the electric potential energy per unit charge.
Key Relationships:
- • V = I × R (Ohm's Law)
- • P = V × I (Power)
- • E = V × Q (Energy)
- • V = W / Q (Work per charge)
Practical Applications
Power Systems
Transmission lines use high voltages (138kV-765kV) to reduce power losses over long distances.
Electronics
Microelectronics operate at low voltages (1.2V-5V) for efficiency and safety.
Industrial
Motors and industrial equipment typically use 480V-4160V three-phase systems.
