Understanding Voltage Units
Voltage (electric potential difference) is measured in Volts (V), the SI unit named after Alessandro Volta. It represents the energy per unit charge required to move a charge between two points.
Common Voltage Units:
- Volt (V): SI base unit of electric potential
- Millivolt (mV): 1/1,000 of a volt — used in sensors and biomedical signals
- Microvolt (µV): 1/1,000,000 of a volt — used in EEG and precision measurements
- Kilovolt (kV): 1,000 volts — used in power transmission and X-ray machines
- Megavolt (MV): 1,000,000 volts — used in lightning and high-voltage research
Common Reference Voltages:
- AA Battery: 1.5 V
- USB: 5 V
- Car Battery: 12 V
- Household Outlet (US): 120 V
- Household Outlet (EU): 230 V
- Power Lines: 110–765 kV
