Orders of magnitude (voltage)

This is for comparison purposes, a set of electrical voltages of different magnitudes. The data can often be understood as a "typical"; the converted values ​​are rounded.

Basic unit of electrical voltage in the international system of units is 1 volt ( unit symbol V), the symbols U.

1 uV to 1 mV

( 0.000001 V - 0.001 V)

  • 5μ to 100 microvolts: voltages measured at an EEG

1 mV to 1 V

(0.001 V - 1 V)

  • Few mV: voltages measured at an EKG
  • To 50 mV: zeta potential of particles

1 V to 1 kV

(1 V - 1,000 V)

  • To 4 V: electric potential of a galvanic cell (battery): 1.24 V NiCd or NiMH single cell
  • 1.50 V: Alkaline D cell
  • 2.00 V: lead-acid cell
  • 3.60 V: Lithium cell ( button cell)
  • Batteries and accumulators series of mono cells: 9 volt block ( 6F22)
  • 12 V: Starter Battery in car ( battery)
  • 24 V: Starter Battery in truck ( battery)
  • Low voltage systems: 12 V halogen lamp
  • Power grids to supply private households: 100 V in Japan
  • 110 V in the U.S.
  • 220 V in Russia
  • 230 V in the European Union
  • 500-800 V: tram, subway and trolley bus in the industrial use of the three-phase AC voltage equal to 500V is mostly used.

1 kV to 1 MV

(1,000 V - V 1,000,000 )

  • 5-25 kV Medium voltage supply networks
  • 15-25 kV: Operating Voltage of several railways
  • 110, 220, 380 kV: high and extra high voltage grid to the continental capacity balancing

1 MV and 1 GV

( 1,000,000 V - 1,000,000,000 V)

1 to 1 GV TV

( 1,000,000,000 V - V 1,000,000,000,000 )
