Electrical Units of Measure. The standard SI units used for the measurement of voltage, current and resistance are the Volt [ V ], Ampere [ A ] and Ohm [ Ï ] respectively.0 -12. So to display the units or multiples of units for either Resistance, Current or Voltage we would use as an example: 1  1kV = 1 kilo-volt â which is equal to 1,000 Volts. 2  1mA = 1 milli-amp â which is equal to one thousandths (1/1000) of an Ampere.
